Also, hot air is less dense. Convert temperature to Celcius (-32 * 5/9)
add 273 to convert to Kelvin. Take 273 and divide by the Kelvin
tempature to get this ratio. EG 30 Celcius (86 Ferenheit) has a ratio
of 273/373 dry air density (0% humidity). Also, warmer air can hold
more water vapor as tempature rised. A dew point of 65 degree Farenheit
means the air, if cooled to 65 F, would be at 100%. Warm the air to 90
with that days sun and the humidity is 60% with the same amount of
moisture in it. Take it to 212 F 100 C and 100% humidty means 100%
water vapor, 0% nitrogen, 0% oxygen. There are water vapor tables that
can tell you at what tempatures 100% humidity means as far as percent
water and percentage air.

Putting the science aside, I love riding in hot humid weather. I feel cool
when riding because of the air flow around me. I like it when I look down
at the water bottles and have sweat drip off my chin. When I roll up to a
stop sign is like walking in to an oven. My arm and leg instantly get wet
with sweat. It makes me feel really strong. ( ha ha)

Yesterday it was around 90 deg F and very humid in Oshkosh and I rode 51
miles. I drank about twice as much as I usually do, about two water bottles
an hour.

Make sure you're getting plenty of electrolytes. Drinking two
bottles of plain water is a recipe for hyponatremia, whihc is not
pleasant.
