September historically is one of our most pleasant months and 2025 largely held true to that.<\/p>\n<p>We did start out pretty mild and precipitation was meager for the first half of the month. Finally, on the 13th, we began to see things cool down and then on the 16th got a nice shot of rain (0.61\u201d).<\/p>\n<p>The rest of the month offered mild but comfortable temperatures. A strong trough on the 23rd cooled us considerably with that day offering high temperatures nearly 20 degrees below normal. It also brought a very healthy shot of rain (1.21&#8243;).<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/www.thorntonweather.com\/blog\/thornton-weather\/september-2025-top-shots-monthly-photo-slideshow\/\">September 2025 in pictures \u2013 view the monthly photo slideshow<\/a><\/strong><\/li>\n<\/ul>\n<p>In the end, the average temperature for the month of September ended up very close to average.
