Climate - Sequim (Washington_state)

---

The climate of Sequim is sub-oceanic, with quite mild, rainy winters and mild, fairly sunny summers.
The town is located in the north of Washington state, on the coast of Juan de Fuca Strait, beyond which lies Canada. Seattle is located 75 km (45 mi) to the southeast.
Even though we are in a cool and humid area, the city has an arid and sunny microclimate because it is protected from the southwest winds by the Olympic Mountains.
Although the winter is mild enough, there can sometimes be cold waves, sometimes even in November, with lows going down to -10 °C (14 °F) or even below.
Snow, already rare in the area due to the prevalence of mild currents from the ocean, is even more so in Sequim due to the arid microclimate: just 4 cm (1.6 in) of snow fall in a year. However, occasionally there can be a heavy snowfall, as happened in February 2011 and 2019.
In summer, it rarely gets hot because of the influence of the ocean, and even when it does, the temperature drops a lot at night. Generally, the temperature does not go above 33/34 °C (91/93 °F) on the hottest days, but sometimes it does not even reach 30 °C (86 °F) for a whole month.
The average temperature of the coldest month (December) is of 3.6 °C (38 °F), that of the warmest months (July, August) is of 15.5 °C (60 °F). Here are the average temperatures.

Precipitation amounts to 410 millimeters (16.1 inches) per year: it is therefore quite scarce. It ranges from 15 mm (0.6 in) in the driest months (July, August) to 70 mm (2.8 in) in the wettest (November). Here is the average precipitation.

The sea temperature ranges between 8 °C (46 °F) and 14 °C (57 °F). So, it is cold all year round. Here are the average sea temperatures.

Best Time

The best time to visit Sequim is summer, especially in July and August, since it is the mildest, driest and sunniest period of the year. May, June and September are also acceptable months.
