Water slide weather in O'Fallon runs May through September. About 120 days a year reach 80°F — the point where a wet slide feels like summer rather than a dare — and July is the warmest month, with highs around 88°F. Outside that window the same units run dry, so a slide still works for a fall festival or a school event.
