Comfortable May Dew Points
Posted: 17 May 2024 05:30 AM, Views: 896
The featured chart presents an IEM computed maximum hourly dew point temperature for Des Moines between 1 and 16 May each year on record. The max dew point for this May is only 61°F, which matches the minimum for a couple of recent years. A noticeable plot outlier is 2010, which had a number of chilly days during the first half of the month. This is a good time of year for warm temperatures and not too bad humidity levels. This certainly changes as we move toward June, so get out to enjoy it now!
