Does A Base Layer Keep A Rider Cooler in Hot Weather

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Not usually for the arms. Besides, the base layer looks better, and provides value off the bike too.

This July has been strange because we haven't had any monsoons. In my area of town, we haven't had a drop of rain since 3/18.
It sure has been a hot & dry July. The night temps have also not dipped below 90F for 19 days straight until this Sunday night. Yesterday it cooled a bit and was a bit overcast with Cali fire smoke and more humid which allowed for extended riding.

Starting rides around sunset when it is 110F is great as the low to no sun makes a huge difference and it only gets cooler as the rides goes on. Starting at 100F in the morning for a long ride is a poor idea.

I too cycle to work for the past 17 years and typically leave work for home at 4pm for a 12mi commute. Under 108F is great. Over 115F is where it one really starts to cook. I've had several rides home 118-120F which would likely be impossible if I had not acclimated through the spring.

I think people moved South to escape the horrible winters, because A/C allowed them to tolerate the awful summers of the Sun Belt, but if those winters become less horrible and those summers become more awful, what's the attraction? I was astonished a few years back when it was so hot in Phoenix that they had to halt air traffic, because the air was too thin to provide lift.

I think it depends a lot on the hot weather. If the humidity is low, i think having an extra layer of something similar to columbia omnifreeze actually helps quite a bit. That said, in very humid and warm conditions it just feels warmer. Just my not very scientific observations. Of course, your mileage may vary. I’m a rather inefficient sweater so i have no problem keeping a base layer damp.

You guys need some of this air (temps are in °F, the graphic is confusing.) Temps/forecast are for this week - August, 2020.
They actually hit -105 °F a couple of days ago.

I love seeing theses threads about riding in hot weather, and have people dismiss the heat in AZ, because "it's a dry heat".
