IEM Daily Feature

Hours of 20+ MPH


Posted: 03 Apr 2025 05:30 AM, Views: 502
Winds on Wednesday were once again quite windy with gusts topping 50 MPH for some parts of the state. So the daily feature is once again attempting to quantify if this year has been windier than average or even the windiest on record as many Iowans continue to believe. The featured chart presents the number of hours for the year to date period with a sustained wind speed of at least 20 MPH. While this year's value falls just outside of the top 10, it certainly is above average with the bottom panel showing the hourly frequency above average for nearby all of the daylight hours of the day. Of course, there is no one simple metric to answer the question on how windy it has been this year. This website certainly offers a number of "autoplot" tools to investigate this yourself as you can follow the "generate chart" button on this feature and turn knobs until you find 2025 on top!
