Jacksonville summers are hot, humid and stormy. Plan around three things.
1. Heat index, not temperature
At 90°F with high humidity, the heat index can pass 105°F. That is when heat exhaustion risk climbs. Early mornings (6 to 10 AM) and evenings under lights (after 6 PM) are the sweet spots. The City of Jacksonville closes its staffed complexes from noon to 3 PM daily.
2. Afternoon storms
Sea-breeze thunderstorms often build between 2 and 6 PM. If you hear thunder, get off the court and wait 30 minutes after the last rumble.
3. Surface
Clay courts (Har-Tru) stay cooler than hard courts and are easier on joints.
