Winter Spring Summer Fall


Spring

Spring is mostly wet, mild, and often windy. Higher elevations are cooler with some snow. Temperatures usually range from 35 degrees Fahrenheit to 60 degrees Fahrenheit. The Olympic Peninsula has a climate conducive to flower growing and the color show in spring is usually quite spectacular.


Summer

Summer is generally fair and warm. Afternoon temperatures in the warmest summer months average from 65 degrees Fahrenheit to 70 degrees Fahrenheit, occasionally reaching 80 degrees Fahrenheit. A temperature of 85 degrees Fahrenheit is considered unusually warm. Nighttime temperatures can drop as low as 45 degrees Fahrenheit. Frequently, during the latter half of the summer and early fall, fog banks and low clouds form over the ocean and move inland at night. Tops of the clouds are generally below 3000 feet; thus higher elevations are sometimes clear while the lower valleys are filled with fog. Fog sometimes disappears before mid-day. On most summer afternoons near the water, a moderate to cool breeze can be expected. A few thunderstorms usually occur each summer, especially in the higher elevations. Normally very little rain falls during the summer months but it has also been known to rain for several days during this period.


Fall

Fall is usually cool and wet with occasional winds. Early snowstorms are possible in the mountains. Temperatures usually range from 35 degrees Fahrenheit to 65 degrees Fahrenheit. Frequently, during the latter half of summer and early fall, fog banks and low clouds form over the ocean and move inland at night and usually burns off by mid-day.


Winter

During winter season, afternoon temperatures are in the 40's Fahrenheit and nighttime readings are usually in the upper 20's or lower 30's. Windstorms can occur. In lower elevations and near the water, snow seldom reaches a depth in excess of six to ten inches or remains on the ground more than a few days. However, snowfall and depth on the ground increases dramatically along the slopes and tops of the mountains, with Hurricane Ridge averaging 400 inches of snowfall each year.
