Trick Or Treat, Mother Nature: 2021 Halloween Forecast In Boulder

BOULDER, CO — Before the city's cutest witches and goblins take to Boulder streets in search of Halloween's sweetest bounty, it's a good idea for parents to check out what Mother Nature has in store for our community's annual trick-or-treating festivities.

Trick-or-treating in Boulder is planned for the evening of Sunday, Oct. 31. Considering the event is just days away, you might want to plan ahead and bring extra umbrellas and jackets on your neighborhood trek.

As you head out on Sunday evening, expect clouds and chilly temperatures. AccuWeather predicts that temperatures will dip to 31 degrees in the evening, down from a high of 48 degrees.

Though you may luck out and not need those umbrellas and jackets, you should bring them just in case — the chance of precipitation is currently 56 percent, and rain may mix with — or change to — snow, AccuWeather is predicting.

Though Halloween is expected to be chilly, the days leading up to the holiday will be significantly warmer. Temperatures from Thursday to Saturday will reach the mid- to high-60s in Boulder.
