In the last few years, Denver has recorded the last freeze of the season between April 23 and May 22. If Denver does not fall below freezing again this season, the last freeze of 2024 will be May 4, when Denver fell to a low of 31 degrees.

Since Mother’s Day falls on the second Sunday of May, that’s why residents are generally safe to plant outside after Mother’s Day.
