I don't like hot, humid weather but I'm stuck with it about 4 months out of the year living in NC. Here are my strategies:

- Ride early in the morning if possible.
- Wear breathable, wicking cycling clothes.
- Drink plenty of fluids. Cold water works much better for me, so I use insulated water bottles largely filled with ice.
- Choose routes that stay in the shade as much as possible.
- Avoid routes with lots of traffic lights. The hottest part of my commute is sitting at red lights.
- Try to avoid hills if possible. You generate a lot of body heat riding up hills.
- Wear bright clothes, not black or other dark colors.
- Keep moving as much as possible. The wind generated from moving helps cool you down.
