Live official NWS planning
Best time to watch the Seafair Air Show
Comparing the published air-show performance hours over Lake Washington with the newest official National Weather Service hourly forecast. The planner refreshes as rain, visibility and wind conditions change.
This identifies a better weather window during published air-show hours, not a promise that conditions are safe, that a flight will occur or that the schedule will stay unchanged. Follow NWS warnings, Seafair announcements, pilots, event officials and local emergency instructions.
Weather-aware preparation
What to check before leaving
Visibility and clouds
Check the latest hourly forecast and current reported visibility. Pilots and event officials determine whether conditions support each demonstration.
Wind and lake conditions
Recheck wind and radar before the flying program. Weather over Lake Washington can affect aircraft, parachute, rescue and hydroplane demonstrations differently.
Sun and rain
Bring weather-appropriate sun or rain protection allowed by the official event rules. The Seafair FAQ lists personal umbrellas, sunscreen and sealed nonalcoholic drinks as permitted.
