Oh My Gosh It Got Hot Quick!

Why is Dewpoint Important for Runners?

If you live in Texas, you know that we just went from rain, rain, rain to hot, hot, hot with nothing in between. Summer in Texas is always crazy. Runners are the first to understand that hot weather can cause bad things to happen on a run. But heat from the sun isn’t the only contributor. Dewpoint is a deciding factor on how the body will react to the environment.

Dewpoint is how much moisture is in the air, which easily translates into how it’ll feel outside. I try to check the dewpoint first thing before I step out to run.  You can find the dewpoint on most weather apps. Refer to the chart below to help you understand how the dewpoint number might affect your run.

Table indicating how dew point affects comfortability.

Once you get into 60+ ranges you can plan accordingly. The higher the number means the more moisture in the air and the harder it is for sweat to evaporate off the body and cool you off. 

There are things you can do to minimize discomfort.

1. Slow your pace to adjust for the body working hard to cool itself down

2. Drink and rehydrate

3. Run in the shade and wear a hat

4. Wear moisture wicking clothes 

Summer runs can be successful as long as you are aware and prepared.
