From the books of Geography Seattle is well known for its rain and dark, gloomy skies, but it may surprise many how pleasant the weather can be, particularly during the summer months. Using data from meteorological services for the past 50 years, we can conclude that November through March brings cool temperatures, heavy cloud cover and rain falling on most days. The coldest month is January with average lows in the mid to upper 30s F (about 3°C). Weather is pleasant from April through October, with the best weather in July and August when highs average in the 70s and rain is uncommon. Skies are mostly clear and smog-free, though mornings can produce an on-shore flow resulting in low clouds and fog which typically burns off by mid-day.
