Can I use a splash pad after rain?

Splash pads are engineered to drain rainwater fast — sloped surfaces, perimeter drains, and grates handle most storms in 15-30 minutes. Recirculating systems briefly halt during rain to prevent dilution and contamination but resume quickly afterward. Heavy storms or flash floods can wash debris, fertilizer, and bacteria onto the pad; staffed facilities test water quality before reopening, which can take an hour or two. The bigger weather concern is lightning. Most pads close at the first thunder and reopen 30 minutes after the last strike — the U.S. National Weather Service 30-30 rule. After hurricanes, tropical storms, or major flooding events, pads may stay closed for days for full sanitation. Check your parks department's social media or hotline.
