Planning your visit or a stroll through Port Townsend? Here you will find the most up-to-date weather information, detailed charts, and upcoming forecasts.

The climate in Port Townsend can be described as temperate maritime, characterized by its mildness and lack of extreme temperatures. Thanks to its coastal location, it avoids sweltering heat in summer or harsh frosts in winter, making the city an attractive destination almost any time of year, provided you prepare for the conditions.

Throughout the year, there is a clear distinction between the wet and dry seasons. Summer, especially July and August, offers travelers the most comfortable weather: average temperatures reach 17–20°C, and the number of rainy days is minimal. This is the ideal time for outdoor activities and exploring sights in the fresh air.

Conversely, the winter period is characterized by cool temperatures and high humidity. From November to January, the air temperature usually hovers around 4–7°C, and the number of days with precipitation can reach 20 per month. While the rain is frequent, it creates the unique atmosphere of a cozy seaside town, perfect for a peaceful getaway.

The weather in Port Townsend is remarkably stable and mild, characteristic of a maritime climate. You won't encounter extreme temperature fluctuations here; the annual range is quite narrow. Winters pass without harsh frosts, remaining cool and damp. February is typically the coldest month, when night temperatures can drop to 3°C and daytime highs rarely exceed 6–7°C. December and January show a similar pattern, with average values around 5°C, requiring travelers to have warm, windproof clothing.

The summer period in this region is a time of pleasant warmth without sweltering heat. July and August are traditionally the warmest months, when the mercury reaches its peak, rising to a comfortable average of 20°C during the day. This weather is ideal for outdoor activities and walks, as the air stays fresh. The shoulder seasons, spring and autumn, are characterized by a gradual rise or fall in temperature, ranging on average from 8°C in April to 15°C in September.

A hallmark of the local climate is the small range of daily temperature fluctuations. The difference between day and night temperatures here is insignificant and rarely exceeds 3–5 degrees. Even in the height of summer, when days get warmer, nights remain bracing with temperatures around 14°C. This creates a predictable atmosphere; however, tourists are always advised to keep a light jacket on hand, as the proximity to the ocean prevents the air from warming up significantly, even in the evenings.

Port Townsend's climate is characterized by distinct seasonal precipitation, where wet winters transition into relatively dry summers. If you are planning a trip during the winter months, especially in December and January, be prepared for frequent precipitation: this period sees the highest number of rainy days—up to 21 days per month. Overcast skies prevail this time of year, and rain tends to be persistent, though snow is rare thanks to the mild temperatures.

The most favorable and driest time to visit is during the summer months. July and August is the period when the probability of precipitation is minimal, with rain occurring on average only 7–8 days per month. This is the best time for outdoor sightseeing and walking along the waterfront, as the sun appears much more often than in other seasons.

Spring and autumn are transitional periods with moderate moisture levels. In March, April, and October, it rains for about half the month (around 16–17 days). It is worth noting that even in the wettest months, the total volume of precipitation is distributed fairly evenly, often falling as light drizzle or short showers, which is typical for this region.

Given the temperate maritime climate of Port Townsend, the weather can be quite changeable, so the primary principle for packing is layering. Even in the warmest summer months, temperatures rarely exceed 20°C, and evenings are often cool. Be sure to bring T-shirts, light sweaters, and fleece jackets that can be easily layered or removed as needed.

Special attention should be paid to protection from moisture and wind. Statistics show that rain is frequent, especially from October to March, when the number of rainy days reaches 20 per month. A high-quality waterproof windbreaker with a hood or a good raincoat will be your indispensable companions. An umbrella might also come in handy, but due to the winds off the bay, a sturdy jacket is often more practical. Choose comfortable shoes for long walks, preferably waterproof.

If you are planning a summer trip when rainfall decreases significantly, your luggage can be lighter, but a warm layer is still necessary for evening walks by the water. Don't forget sunscreen and sunglasses: even in cloudy weather and moderate temperatures, the sun near the water can be intense. A snug hat that stays on in the sea breeze will also be useful.
