Climate chart - Forks (Washington_state)
The climate of Forks is sub-oceanic, with quite mild, very rainy winters and mild, quite sunny summers.
The town is located in northwestern Washington state, 18 km (11 miles) away from the ocean, and west of the Olympic Mountains. We are in a particularly humid and rainy area. In the contiguous United States, there are no other lowland areas that are so rainy: you have to go to Alaska or Hawaii.
Although the temperatures are not usually very low, wind, humidity and rain exacerbate the feeling of cold. In spring, the temperature rises slowly, and in May, there are still very cool, rainy days. In late spring and summer, fog can form at night and in the early morning. In summer, however, there are many nice days.
Occasionally in winter, sometimes even as early as November, there may be cold spells, in which the temperature can drop down to -7/-8 °C (18/19 °F) or even below.
Given the generally mild climate, snowfalls are rare, however, a more abundant snowfall than usual can occasionally occur. In a year, 20 cm (8 in) of snow fall.
In summer, it rarely gets hot. On the hottest days of the year, the temperature can reach 32/33 °C, but it may not even reach 30 °C (86 °F) for a whole month. However, in August 1981, it reached 39 °C (102 °F), while during the exceptional heat wave of late June 2021, it reached 43 °C (110 °F).
The average temperature of the coldest month (December) is of 4.3 °C (39.8 °F), that of the warmest month (August) is of 16.8 °C (62.3 °F). Here are the average temperatures.
