August Weather in Iowa

Hot and humid are two words that accurately describe Iowa summers. But “abundant sunshine” and “wind” also apply during the summer months.

Whatever your preference, be prepared for some heat, with cooler temperatures in the evening and overnight. The monthly average high for August in Des Moines ranges from 82-79ºF, according to The Weather Channel. Monthly lows range from 63-58ºF.

While it is too soon to generate a specific forecast for the week of the conference, Aug. 13-17, expect a high around 84ºF, with a low around 65ºF, according to The Weather Channel.

For the latest weather information, including updates on inclement weather or warnings, refer to the National Weather Service.
