🏡 What is the weather like in Sequim, and how does it affect retirees?

The weather in the Sequim, Washington area is one of the major reasons so many retirees find it the perfect place to retire. Sequim is located in the famous Blue Hole, aka The Rain Shadow, where the annual precipitation is only 16 inches per year compared to Seattle's 45 inches per year. There is an extraordinary weather pattern that keeps a hole in the clouds above Sequim with a radius that extends roughly seven miles around Sequim to the west and north. The mountain elevation to the south of Sequim get outside that range. The climate is unusually mild with a very even temperature all year long.

🏡 What percentage of the year are within recorded temperature ranges in Sequim?

Summer Comfort: July and August are the warmest months, with average highs of 68°F–73.1°F and lows around 52.3°F, described as “comfortable” and ideal for outdoor activities.

Winter Mildness: Winter highs average 47.9°F–48.5°F, with lows around 30.9°F–34.7°F, milder than many Pacific Northwest locations due to the rain shadow effect.

This contrasts with December’s 2.3 hours daily, but the lack of extreme heat or cold keeps conditions livable year-round.

🏡 How does the mild weather in Sequim effect retirees?

Seasonal Appeal for Retirees: The mild climate, especially from May to September, supports outdoor activities like hiking, golfing, and visiting the Lavender Festival, which aligns with retirees’ interests in active lifestyles. Winter’s cooler temperatures (highs in the 40s) are still manageable for those accustomed to milder climates. Data Limitations: Exact daily counts for the 50°F–80°F range are not provided in the sources, so the 50%–60% estimate is based on monthly averages and seasonal trends. For precise data, you could consult historical weather records from NOAA or local weather stations like Sequim Valley Airport. Practical Advice: Retirees concerned about mildness should note that summer days often require a light jacket due to cool breezes from the Strait of Juan de Fuca, and winter’s grey, overcast skies may affect those sensitive to seasonal affective disorder.
