Rain in Olympia: What You Need to Know
Olympia, Washington experiences Pacific marine climate with 150+ rain days per year. The Olympia rain radar delivers real-time precipitation data from KATX (Camano Island), updated every 4–6 minutes at up to 250-meter resolution — showing exactly when and where rain will arrive, not just whether it might.
Storms in this part of Washington typically approach from southwest off Puget Sound and Pacific. RainViewer's hyperlocal radar includes direction arrows and a 2-hour nowcast, so residents and visitors in Olympia can make informed decisions about travel, outdoor plans, and weather preparation with real advance notice.
