1972 Washington Climate
WASHINGTON CLIMATE for these counties Clallam, Grays Harbor, Jefferson, Pacific, and Wahkiakum Earl L. Phillips and Wallace R. Donaldson) Summary This five - county area along the Washington coast extends from the Columbia River to the Strait of Juan de Fuca (Figure 1). Most air masses reaching the coast originate over the Pacific Ocean. This maritime air has a moderating influence throughout the year; the daily range in temperature is about 120F in winter and. 250F in summer. In late spring and. summer, westerly to northwesterly winds from over the cold surface of the ocean and the high pressure center covering the North Pacific K contribute to a dry season which begins in late spring and reaches a peak in summer. In late fall and winter, southwesterly and westerly winds from °" "rz M " "" °" over the ocean provide a source of moisture WASHINGTON during the wet season which begins in October, Fig. 1 reaches a peak in winter, and then decreases in spring. Some of the most extreme variations in annual precipitation within short distances in the United States are recorded in these coastal counties. Annual amounts are less than 20 inches in the driest areas of northeastern Clallam and Jefferson counties, and 125 to 200 inches on the western slopes of the Olympic Mountains. Eighty per cent of the annual precipitation falls in the six months, October through March. Precipitation for July and August is less than five per cent of the annual total. 1 Former NOAA Climatologist for Washington and Acting Climatologist, National Weather Service, Seattle. of 80 ,0 60 50 10 30 20 10 Fi�, 2 AVERAGE MAXI III AND MNI'IUPI TE 11"PERATURES Maximum ...r7inimum E 1ma Point Grenville ,JAN FEB P1AIZ APIZ 6IAY JUN JUL AUG SEP OCT NOV DEC Factors Influencing the Climate The climate is influenced by topography, location along the windward coast, the prevailing westerly winds, and the position and intensity of high and low pressure centers over the North Pacific. Elevation varies from sea level to 3, 000 feet in the Willapa Hills and 7, 000 feet in the Olympic Mountains. The area from the ocean beaches to the crest of the Willapa Hills and Olympic Mountains is exposed to the full force of the Pacific winter storms. Gale force winds and heavy precipita- tion occur each winter. To the east, the Cascade and Rocky Mountains shield the area from outbreaks of cold arctic air in winter and hot dry air in summer. Temperature During the warmest summer months, afternoon temperatures near the coast are in the upper 60's, increasing to the 70's in the interior valleys (Table 2). In the mountains, temperatures decrease about 30F with each 1, 000 feet increase in elevation. Maximums exceed 80OF on three to ten days in July and August, and reach 90OF on two to five days (Table 4a). Minimums are in the 40's and lower 50's, producing a daily range of about 250F (Figure 2). The highest temperatures are recorded when air from the interior of the continent reaches the coast. In an average winter, maximum temperatures range from 380 to 450F and minimums from 280 to 350F (Table 2). Maximums are below freezing on one to three days and minimums drop to 20OF or lower on one to five nights (Table 4b). During colder winters, minimums have dropped to 200F on five to twenty nights and to 100F on three to ten nights (Table 4d). The percentage of maximum and minimum tempera- tures within 5 0 F increments by weeks and. the average maximums and minimums with the standard deviation (a statistical indication of variability) are given in Tables 4f -i. As an example, in 35 years at Aberdeen, 32 per cent of the minimum temperatures during the week beginning January 3 were between 300 and 340F. The coldest weather occurs with outbreaks of arctic air, frequently accompanied by clear skies and dry northeast winds. The percentage of daily maximum and minimum temperatures exceeding selected values is given in Table 4e. For example, at Aberdeen, maximum temperatures in the week beginning July 12 reached 970F on 2 per cent of the days and 80OF or higher on 10 per cent of the days. In the week beginning January 17, minimums dropped to 130F on 2 per cent of the nights and to 230F or lower on 10 per cent of the nights. Relative Humidity, Wet Bulb and Dry Bulb Temperatures In summer, the average daily range in relative humidity is from 60 per cent in the afternoon to 90 per cent at night and in winter from 75 per cent to 90 per cent. Along the coast and Strait, the percentages are slightly higher (Table 7). The mean and distribution of the hourly dry -bulb, wet -bulb, and dewpoint tempera- tures recorded at Hoquiam and Olympia are given in Tables 5a, 5b, and 6. Wet -bulb temperature is the temperature to which air at a constant pressure may be cooled by evaporating water into it until saturation occurs. Dewpoint is the temperature to which air must be cooled at a constant pressure and water vapor content in order for saturation to occur. The wet -bulb temperature exceeds 650F 1 per cent of the time at Hoquiam and 3 per cent of the time at Olympia. It exceeds 60 °F 15 per cent of the time over most of this area in the four warmest months. June through September. Surface Water Temperature The temperature of the ocean and the inland waters of the Puget Sound is recorded from samples taken 1 foot below the surface. Most temperature data are from tide recording stations. In the open ocean near the Washington coast, the average temper- ature of the surface water is about 480F in February, 520F in May, 570F in August and 50 °F in November. The range of temperature is greater on shallow and protected bays along the coast and Puget Sound. In the deeper areas of the Sound and the Strait, where there is good circulation of water, the annual range of temperature is about 100F (Table 8). 22 20 18 16 14 12 10 8 6 4 2 b Fig. .i AVERAGE MONTHLY PRECIPITATION (Inches) JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC Precipitation Precipitation is light in summer, increases in fall, reaches a peak in winter, and then gradually decreases in the spring (Figure 3). The lifting and cooling of moist air rising along the windward slopes of the Willapa Hills and Olympic Mountains results in a belt of heavy precipitation from the coast to the crest. During the wet season, rainfall is mostly moderate or light in intensity and continuous rather than heavy showers. Annual amounts range from 70 to 100 inches over the coastal plains and from 125 to 200 inches in the "rain forest" area on the western slope of the Olympic Mountains (Figure 4). The heaviest rainfall during a single storm was 12 inches in 24 hours; 23. 5 inches in 48 hours; 28. 6 inches in 72 hours; and 35 inches in four days recorded at Quinault Ranger Station, January 21 -24, 1935. Warming and drying of air descending the lee slope of the Olympic Mountains produces a light rainfall belt - -a rain shadow - -on the northeastern Olympic Peninsula. Drizzle or light rain frequently falls in this area at the same time that the "rain forest" experiences moderate or heavy rainfall. In the lowlands along the Strait of Juan de Fuca, annual precipitation increases from about 18 inches near Port Townsend and Sequim, to 25 inches at Port Angeles, and to 100 inches at Neah Bay (Figure 4).

Extreme monthly, weekly, daily, and hourly amounts are given in Tables 12a, b, c, and d. The variability of daily, monthly, and, annual precipitation is given in Tables 13 and 14 and Figures 5 and 6. In Table 13, frequencies for specific amounts are given. For example, at Aberdeen the total precipitation for July is less than .1 inch in one summer out of 10; also, it exceeds 3. 5 inches in one summer out of 10. Annual precipitation is less than 70 inches in one year out of 10; also it exceeds 102 inches in one year out of 10. The probability of receiving specific amounts of precipitation during any one -, two -, or three -week period is given for Aberdeen and Sequim in Tables 14a and b. As an example, at Aberdeen, the average precipitation for the week beginning March 1 is 1. 98 inches (Table 14a). There is a 5 per cent chance (1 year in 20) of receiving no Fig. 5 DEPARTURE OF ANNUAL PRECIPITATION FROM AVERAGE FOR PERIOD 1891 -1969 ABERDEEN, WASHINGTON Precipitation 82.87 inches V1 O 1n O N O Ln O N O Ln O N O N O T O O N N M M Q C V1 V1 %D 10 n oo M 01 M M 01 M 01 01 M 01 01 C'1 01 M Ol 1 + g + 4 N u u 0 a M - 4 - 8 Fig. 6 DEPARTURE OF ANNUAL PRECIPITATION FROM AVERAGE FOR PERIOD 1898 -1968 PORT TOWNSEND, WASHINGTON Average precipitation 18.34 inches. to O N O in O VI O 1!f O to O 1A O N O C1 O O -4 N N M M Q N M %0 10 n 00 01 Ol C1 A C1 M C1 M 01 01 01 O 01 a1 O precipitation or only a trace, and a 67 per cent chance (20 years out of 30) of receiving 1. 00 inch or more. Measurable precipitation (. 01 inch or more) is recorded on 4 to 10 days each month in summer, 10 to 18 days each month in spring and fall, and 18 to 25 days each month in winter. The average and greatest number of days with precipitation amounts of . 01, . 10, . 50, and 1. 00 inch or more, are given in Tables 15a and b. The frequency of hourly rainfall of various intensities is given for Aberdeen 20NNE and Port Angeles in Tables 16 a and b. Maximum intensities for short time intervals are given in Table 17 and Figure 7. Thunderstorms occur on 5 to 15 days each year. The greatest number are in the mountains during the summer, however, they have been reported in all months. Hail of sufficient size or intensity to cause crop or property damage is rarely, if ever, reported.. Snowfall Most winter precipitation falls as rain in elevations below 1, 000 feet, as rain and snow between 1, 000 and 2, 500 feet, and as snow in the higher mountains. In the Olympic Mountains, snow can be expected to arrive in October and to remain on the ground from November until June or July. The highest peaks are snowcapped. most of the year and Blue Glacier, near the summit of Mt. Olympus, covers about 1. 6 square miles. Winter season snowfall is from 8 to 30 inches in the lowlands. It gradually increases with altitude to 500 inches near the crest of the Olympic Mountains (Tables 18, 19, 20). On Blue Glacier (elevation 6, 900 feet), 542 inches of snowfall was recorded in the 1957 -58 season. This is the only complete winter season snowfall record available in the higher elevations. During this period, precipitation in the lowlands was about 15 per cent below normal.

Maximum depths to expect are 15 to 30 inches in the lowlands, 30 to 60 inches in the foothills, and 100 to 200 inches in elevations above 4, 000 feet. In the mountains, the density of the snow pack increases from about 30 per cent water in early winter to 40 per cent in April. Snow depths and water equivalents are given in Tables 21, 22, 23. Flooding The primary period of high stream flow is in late fall and winter, coinciding with the the season of maximum precipitation. Streams may rise above flood stage several times each rainy season. Most rivers, other than the Chehalis, are short and swift, thus they rise and recede rapidly. Frost Penetration in the Soil The depth of frost in the soil varies from winter to winter. It is influenced by distance from the ocean, exposure, elevation, vegetation, soil type, snow cover, and tempera- ture. In the lowlands, frost reaches depths of to 6 inches almost every winter and may reach 15 inches or more in exposed areas during extended outbreaks of cold air and no snow cover. Soils under the mountain snow pack are usually free of frost. Cloudiness, Sunshine, and Solar Radiation The number of clear or only partly cloudy days each month is from 4 to 7 in winter, 8 to 15 in spring and fall, and 15 to 20 in summer. The amount of sunshine received is approximately 20 per cent in winter, 30 to 50 per cent in spring and fall, and 50 to 65 per cent in summer. Frequently in summer and fall, low clouds or fog form over the ocean, move inland at night, and disappear by the following noon (Tables 24a and b). Solar radiation measurements at Astoria, Oregon, are given in Tables 27b and c. This is a measurement of both radiation from the sun (direct solar radiation) and of radiation from scattering in the atmosphere (diffused sky radiation). A langley is a unit of heat measurement and denotes one gram calorie per square centimeter of surface. Wind. The prevailing direction of the wind over the eastern part of the Pacific at this latitude is southwest to west in the fall and winter, shifting to west and northwest in spring and summer. The strongest winds are associated with the more intense winter storms moving east across the ocean. In winter, circulation of air around the low centers approaching the land results in a high frequency of strong southeasterly and southerly winds along the coast and strong easterly winds in the Strait of Juan de Fuca (Table 25, Figure 8). is Fig. g SURFACE WIND ROSES FOR WASHINGTON STATIONS / TATOOSH ISLAND(I) 2 WHIDBY ISL (2) ' TANUARY Y (O MOCLIPS (I) NORTH HEAI� TATOOSH ISLAND(l) `, \ BELLINGHAM (1) bSCALE (IN PERCENT OF TIME) CHEHALIS (1) CASTLE ROCK (1) ,KELSO (2) iWL(2)' ( _i'_ ISL (2) -JULY MOCLIPS (1) 4 � f / TATOOSH ISLAND (1) 6 WHIDBY 1 ISL(2)' 1 -4e NORTH DALLES (1) BELLINGHAM (1) EVERETT (2) PORT ANGELES (2) \ ANNUAL NORTH HEAD (I) *NORTH BEND (1) TACOMA (2) 32 CHEHALIS (1) CASTLE ROCK (1) NORTH HEAD j7�`- --- -�^ (1) 8 32 •T 2� KELSO (2) NORTH DALLES (1) MOCLIPS (1) BELLINGHAM (1) EVERETT (2) 4\7 RTH BEND (I) "N -O b TACOMA (2) HOQUTAM (2) 29 CHEHALIS (1) j_.CASTLE ROCK (1) (2) X31 - ORTH DALLES (1) Branch of Pow Operotlone - Bonneville Power AOminietrotlo,.

U.S. Department of the I-ow t� In coastal areas, wind velocities ranging from 50 to 70 MPH are reported each winter. Extreme winds at 30 feet above the ground can be expected to reach 80 MPH once in 10 years and 100 MPH once in 100 years. Brief records from an exposed ridge (elevation 2, 000 feet) near Naselle, indicate that wind velocities in excess of 100 MPH occur on the higher exposed ridges almost every winter. On most summer afternoons, the wind is rather light with a sea breeze along the coast and a fresh westerly breeze on the Strait. Heating Degree Days Heating degree days are used to estimate heating requirements for buildings. The base temperature normally used is 650F. The number of heating degree units for any one day is the difference between the average temperature and 650 F. The average temper- ature is the sum of the maximum and minimum divided by 2. There are no heating degree days if the average temperature is 650F or higher. Total heating degree days for the season July through June is 5, 000 to 6, 000 over most of the lowlands and increases to 7, 000 or more in the higher elevations of the Olympic Mountains. Heating degree days in Table 28 were computed from monthly mean temperatures. Growing Degree Days Growing degree days, sometimes called heat units, are used to estimate the rate of growth and. development of crops. The most frequently used temperatures are 40 °F for cool season crops and 50 °F for warm season crops. Growing degree days are defined as the difference between the mean temperature for the day and the base tem- perature. The mean temperature for the day is the sum of the maximum and minimum divided. by 2. If the mean temperature is below the base of 40OF or 500F, there are no growing degree days. As an example, on a day when the maximum temperature is 70OF and minimum 500F, the mean temperature would be 600F. There would be 20 growing degree days above a base temperature of 40OF and 10 above a base tempera- ture of 500F. The average number of growing degree days for each month from March through October is given in Table 29 and the weekly values are given in Table 30. These values were computed from monthly and. weekly mean temperatures. Cooling Degree Days Cooling degree days are used to estimate the need for air conditioning and power requirements for cooling equipment. Computation is similar to the heating degree days except that it is the number of degrees above 650F or any base desired. Average weekly values above bases of 600 and 70 °F are given in Table 30. Wind Chill Temperature is not always a reliable indicator of how chilly it is outdoors. Studies i01-- show that heat loss from the body is affected by both temperature and wind. This is wind chill. For example, a 15- mile -an -hour breeze with a thermometer standing at 350F produces the equivalent effect of 160F under calm conditions (Table 4c). Growing Season In most agricultural areas, the growing season is from 160 to 190 days. The shortest, 120 to 140 days, is in the colder cranberry bogs. The date of the last freezing tem- perature varies from mid -April to mid -May. The first freezing temperature in the fall is in October. The probability of below freezing temperatures in the spring and fall is given in Table 31. Evaporation Annual evaporation from a Class A pan is estimated at 25 to 30 inches. Annual loss of water by evaporation from lakes and reservoirs is estimated at 20 to 25 inches. The greatest loss occurs in midsummer. Evapotranspiration "Evapotranspiration" refers to the total loss of water from the soil as a result of evaporation from the soil and transpiration from the growing crop. The rate of growth and development of plants is determined to some extent by the quantity of water transpired. The amount depends on such factors as the type of plant, moisture supply, and the air temperature surrounding the plant. In areas not under irrigation, the quantity of water available to growing plants depends upon the distribution of rainfall during the growing season and the water - storage capacity of the soil within the root zone. Waterholding capacity varies with the soil type. "Potential evapotranspiration" is defined as the maximum amount of water which, if available, could be removed from the soil by the combined processes of evaporation and transpiration under conditions of average temperatures. The term "actual evapotranspiration" is defined as the computed amount of water lost under existing conditions of temperature and precipitation. A comparison of the actual and potential evapotranspiration gives an estimate of the additional moisture plants could use if a moisture deficit did not exist at any time. The Palmer- Havens technique (Thornthwaite method. 1948) was used to compute evapotranspiration at several locations. Assuming the soil has a waterholding capacity of 6 inches in the root zone of crops, estimates of the potential and actual evapotranspiration to expect under average conditions are given in Table 32. Data for Aberdeen and Sequim are illustrated in Figures 9 and 10. !j 14 13 12 11 10 9 � R U 7 G v 6 5 4 3 2 5 4 �3 G \Soil ..
