On October 30, 2025, a Freeze Warning has been issued for the Denver metro area, including Fort Collins, Boulder, and the surrounding suburbs. The warning is in effect from 10 PM on Tuesday, October 29, until 10 AM on Wednesday, October 30.
Overnight, temperatures are forecast to plummet into the teens and lower 20s, with the coldest air settling in before sunrise on Wednesday. These frigid conditions can potentially damage sensitive plants and even outdoor plumbing, prompting officials to advise residents to cover up vegetation and disconnect hoses.
The hard freeze on Wednesday morning will give way to clear and calm skies throughout the day. High pressure is building in, keeping the Denver area dry and seasonally cool, with afternoon highs expected to reach the upper 50s, a bit below normal for late October.

This pattern of dry, cooler-than-average weather is set to continue through the rest of the week. No rain or snow is in the forecast, and traveling around the Front Range should be smooth sailing. Even Halloween night is expected to stay on the chilly side, though conditions will remain dry for trick-or-treating.
By the weekend, a warming trend is expected to arrive, bringing milder afternoons and a little more breeze in the mountains and foothills.
