Halloween Week 2024 FAQ

Here's a guide to the weather during Halloween for the Denver area.

1. When will Denver experience its first stop of the season?
Denver officially reached 32°F on October 25th, marking the first frost of the season. This is about two weeks later than the average first freeze date for the city. However, that was DIA and many places in the area have yet to experience a frost, with some possibly setting records for the most recent first frost in decades.

For the locations that have not yet frozen, this means that the limit has been exceeded for decades. We have the numbers until October 27th. and here are the locations that have achieved or may potentially achieve record drops in two different time steps: since 1990 and since 1970. Blue markers indicate a new record was set in 2024. Red markings indicate that the year 2024 threatens the record.

2. What weather can we expect during Halloween week?
After a mild start to the week, temperatures will drop significantly from Tuesday, with the coldest day expected to be Wednesday. The wind will be annoyingly strong for many of us. An approaching storm system will bring rain and snow to the state, along with significantly cooler temperatures. We expect the first widespread frost for the metro/Front Range areas by Thursday morning.
