Phoenix to open most city splash pads early on March 20 as extreme heat arrives

Early-season cooling option returns as temperatures surge

The City of Phoenix will open most of its municipal splash pads early on Friday, March 20, in response to an extreme heat pattern bringing unusually high temperatures to the region in mid-March. The city’s parks department says the early opening applies to all Phoenix splash pads except those at Edison Park and Nuestro Park, which are scheduled to begin operating later in the season.

For the initial early-opening period, Phoenix splash pads are set to operate Fridays through Sundays from 8 a.m. to 8 p.m. The city’s schedule then expands beginning March 23, when the summer pool season starts and splash pads are expected to shift to seven-days-a-week operations.

What residents should know about hours, exceptions, and access

While most locations follow standard daytime hours, Phoenix lists alternate schedules for two sites. Civic Space Park’s splash pad is scheduled for limited weekday hours and is closed on Sundays, while Altadena Park’s splash pad is also closed on Sundays and operates with different daily hours than the systemwide norm.

The early opening comes as the Valley faces triple-digit temperatures in March—conditions that have already prompted changes in outdoor schedules across the metro area. In spring training, for example, multiple Cactus League games have been rescheduled away from afternoon start times amid forecasts of temperatures reaching or exceeding 100 degrees, with highs projected to climb higher through the week.

• Opening date for most Phoenix splash pads: Friday, March 20, 2026
• Early-opening schedule: Fridays–Sundays, 8 a.m.–8 p.m.
• Seven-day operations scheduled to begin: Monday, March 23, 2026
• Locations opening later: Edison Park and Nuestro Park

Rules and safety measures at splash pads

Phoenix splash pads are designated for water play, not bathing or washing items. The city lists restrictions that include prohibitions on glassware near the pad, bans on animals other than service animals, and limits on food and drinks within a set perimeter. The city also notes that splash pads can be shut down for sanitation issues, and that water features may be turned off during drought conditions.

Officials emphasize that splash pads are one part of a broader heat-safety approach that includes encouraging residents to plan outdoor activity around cooler parts of the day and to use public heat-relief options when needed.

Heat relief context: a broader network beyond parks

Phoenix’s early splash-pad opening aligns with the city’s wider seasonal preparations for heat, which have included expanded cooling options in prior summers, such as designated cooling centers, hydration stations, and a 24/7 overnight heat respite location. The city’s heat-response framework is designed to provide indoor relief alongside outdoor amenities as extreme heat increasingly affects daily routines across the metro.
