In March, Seattle averages a high of 54°F (12°C) and a low of 40°F (4°C). Most runs feel like about 47°F (8°C) once you factor in a typical morning or evening start, so dress for that number rather than the thermometer. Cool, damp, and rarely extreme — Seattle is all about staying dry without overheating.
