Record dewpoints in the St. Louis metro area - July 26, 2026
On Sunday, July 26, the dewpoint at Lambert Airport reached 81°F, setting the all-time record for that location. At 1PM, the dewpoint was 86°F at Washington, Missouri (KFYG) and 85°F at Scott AFB/MidAmerica Airport (KBLV), both potential records for those locations as well. This was my reading using a Kestrel at 2PM in New Baden, Illinois, taken with a camera lens that fogs instantly in these conditions after being in an air-conditioned car:
The effect of evapotranspiration from the corn fields (AKA "corn sweat") is clearly responsible for boosting these values by several degrees. Every time the wind picks up, the values drop 2 or 3 degrees.
The state of Illinois has seen dewpoints of 86°F before in various locations, but this may be the first time these values have been reached in the St. Louis area. Wisconsin holds the all-time record dewpoint for the USA at 90°F.
