Water slide season in Washington
July through early September. Washington's usable wet season is short and sharply split by the Cascades — the east runs genuinely hot and dry in July and August, while the Puget Sound side is milder and the coast stays cool and damp for most of the year.
Ground, anchoring and access
Ground stakes well in much of the state. The constraints are wind on the coast, a shortage of level ground on hillside lots, and soft ground after prolonged rain west of the mountains.
When Washington dates fill
July and August are the season, and those weekends fill first.
Washington State Parks handles state sites; Seattle Parks and Recreation runs city permits.
Not sure where to start? Three of the most-booked slides for Washington events right now are the Longboard 18, the Big Top Bouncer, and the Metro Heroes Combo.
