Seattle

1. General Weather Patterns Related to Daylight

Seattle has a temperate marine climate, characterized by mild, wet winters and relatively dry, warm summers. The city is famous for its overcast skies and frequent drizzle, particularly in the fall, winter, and spring months. While Seattle does not receive as much total rainfall as some might think (about 37 inches annually), the number of cloudy days is significant, with an average of 226 overcast or partly cloudy days per year.

• Cloud Cover: The persistent cloudiness, especially in the fall and winter, can make daylight feel less impactful, even during the day. This is a key factor to consider when planning outdoor activities or adjusting to life in Seattle.
• Rain and Drizzle: Rain is common from October through April, often in the form of light drizzle rather than heavy downpours. This can further reduce the perception of daylight.
