The snow season in Colorado runs July 1 to June 30 and thus today ends the 2024 / 2025 season officially. With the close, we can see Thornton did not fare too well this winter.
We ended up with 36.9 inches for the season. That is far below our 18-season running average of 54.6 inches per season. It also puts the 2024 / 2025 season into the books as the fourth least snowy over that period.
Out at DIA where Denver’s official measurements are taken, they fared better with 47.7 inches. The difference is largely due to a period from November 5 to November 8 in which the bulk of the snow for that event stayed just east of Denver. Over those four days, DIA recorded 18.2 inches versus 10.8 inches here in Thornton.
