Be aware that heat can cause health problems (like heat stroke), so take frequent breaks under shade or inside an air-conditioned environment. Wear light or white breathable clothing, but avoid dark clothing that doesn't breathe well. Check the weather to see what time is cool enough. Mid day is usually the hottest, so avoid mid day. Usually, 2 hours after sunrise or 2 hours before sunset is decent weather. Also, if you can find a night spot with bright street lights, then that'd probably be the coolest option. Make plans to skate on the coolest days of the week and stay inside on the hottest days of the week. When it's too hot out, you can play EA Skate, look for skate spots on Google Maps, or something.
