It's hotter where I live, but it's more humid where you are (my hometown..oh, how I miss Austin), so I think we're both suffering.
I've found that in general, I just can't handle doing much in triple digit temps. I read somewhere about the body *only* being able to cool off by sweat/evaporation once the ambient temp rises over the body temp. Add in your humidity you're going to have a really tough time, so whatever you do, be very careful and pay close attention to your body signs. Look for rapid pulse, feeling faint, *chilled* (I know, seems impossible), disoriented, or just suddenly and extremely fatigued. All can be signs of heat exhaustion and are to be taken seriously. Don't be afraid to call someone to bail you out...you don't want to end up with a heat stroke because you only had one more mile.
Now, what I do to try to keep up some semblance of a cycling routine:
- ride in the morning. I'm not a morning person, but this works better for me than the evenings because the pavement has had a chance to cool down (sort of) overnight. If I try to wait in the evening for everything to cool down, I'll literally be riding at 2 am (which is what my husband does, since he's even less of a morning person, and more of a night person than I am). Even then, I'm not sure it's that cool (although at least then there's *no* sun)
- wet some of your clothes down. Don't wet enough that you make yourself feel cold, or your body is going to have to go from keeping warm to keeping cool, which will be even harder on it. I usually start out my ride with an almost dripping wet bandana wrapped around my head, and another one around my neck (with the wide part in the back...keeping the base of my neck cool seems to really help, plus it keeps me from getting a sunburned neck). Somewhere during my ride I'll stop for water (I ride along a greenbelt/through parks, so I use the watering fountains there) and rewet my bandanas (they dry in about 15 minutes here). At this point I'll also wet down my face and sometimes, depending on how I'm feeling, drip water over my shirt.
- Drink plenty of fluids and electrolytes. If you're sweating a lot, you're losing electrolytes. I ride with a camelbak and put electrolyte replacement powder in my water. You can use an energy/electrolyte sports drink if you like, I just prefer to get my energy from different sources.
- find some way to ice your water enough to keep it cold, but not so much that you're running out of water before it melts. Some people freeze their bottles/camelbaks when they're partially full. My freezer is full at the moment, so I just stuff a lot of ice cubes in my camelbak. We use old-school manual ice trays with largish cubes, and they keep my water cool enough for a couple of hours, but melt in time for me to get to drink all of my water.
- If riding for more than an hour or two, try to build in a stop in some place air conditioned. Allow yourself enough time to get *really* cooled off so that you're not feeling hot and heat fatigued the moment you get back out on the road.
- lower your expectations of what you can do. It's going to take longer in the heat, because of the necessary breaks, and you also may find that you can't push yourself as hard as your normally could (so you'll also be slower). I want to be building up my miles right now, but I'm finding that I can only stand to be out in the heat for so long. I'm not happy about it, but I'd rather ride consistent 10-20 mile rides than nothing at all. Maybe use this time to explore different routes around your area.
