Seasonal opening date

Seasonal opening dates are the single most-asked question parks departments field every spring. The date is set 3–6 months in advance based on staffing, water-system commissioning, and historical weather. Parks departments publish it on the park sign, the city website, and increasingly on the city's social media around mid-April. Most northern cities open splash pads on the Saturday of Memorial Day weekend (late May), regardless of weather. Sunbelt cities open March 1–April 1. Southern California and Florida operate year-round at many sites. Always confirm the date before driving — late-spring cold snaps can push openings back by a week.
