Comfortable Dew Points

Posted: 24 May 2013 05:40 AM

Thursday was a very pleasant day in Iowa with high temperatures near 70 and dew points in the 40s. The featured chart presents the frequency of having a sub 50 degree dew point during the afternoon hours for Des Moines. The top chart is the frequency at a given air temperature, so roughly 50% of the time when the air temperature is 70 degrees in the afternoon, the dew point temperature is below 50. The bottom chart shows the frequency by day of the year. The summer months are certainly the most humid and a sub 50 degree temperature is rare.

Good = 116
Bad = 13
