2025 Daily Highs + Lows
Posted: 08 Oct 2025 05:30 AM, Views: 442The featured chart presents daily high and low temperature climatology for Ames along with 2025 observations. A lot of information is packed into one chart here with the range between the average high and low temperature shaded in green and then the area between those averages and the daily record maximum and minimum values shaded in red and blue respectively. The brown bars are the range between the 2025 daily high and low temperatures. Qualitatively, you can see we have spent very little time this warm season with low temperatures within the blue area (below average). The two cool periods of late August and early September are about all to speak of for such periods since early April.
