Record Heat Expected in Colorado This Week: Triple Digits Ahead

DENVER, Colo. — Colorado is bracing for a heat wave this week, with temperatures expected to soar to 100 degrees or higher in various parts of the state. According to the National Weather Service, the extreme heat will begin Thursday, particularly in southeastern Colorado, including La Junta.

By Friday, regions such as Lamar, Eads, Pueblo, and northern areas like Sterling, Greeley, and Fort Morgan will also experience temperatures near the century mark. Denver could tie or even break its record for the hottest June 20 if it reaches 100 degrees; the current record is 99 degrees, set in 2017.

“We’re looking at high temperatures that could shatter records again,” said Peter Gobel, assistant state climatologist. “Above-normal temperatures are likely, especially in the western part of the state.”

The heat wave comes on the heels of last summer, which was marked by extreme temperatures across Colorado. Many regions, including Grand Junction and Fort Collins, reported record-breaking heat. Climatologists predict a similar trend this year, fueled by climate change factors and dryness.

As temperatures rise, health officials caution residents to prepare for heat-related illnesses, which have seen an increase over recent years. In 2024, heat caused 21 deaths, compared to 13 in 2023. “Extreme heat is the leading weather-related cause of death in the U.S.,” noted Ned Calonge, chief medical officer for the Colorado Department of Public Health and Environment.

With the National Weather Service issuing heat advisories, residents are urged to stay hydrated, avoid outdoor activities during peak heat hours, and check on elderly neighbors and family members.

If you’re planning outdoor activities, it’s best to do so during the cooler parts of the day, ideally early morning or late evening. Heat exhaustion can easily occur if proper precautions aren’t taken, especially for vulnerable groups such as children, pregnant individuals, and those with chronic health conditions.

This week’s forecast indicates that the heat will intensify with highs in the 90s continuing through the weekend. Long-term forecasts suggest that these high temperatures may persist throughout the summer, necessitating ongoing vigilance to protect health and safety.

“We need to rethink how we approach summer with increasing temperatures,” Gobel added, emphasizing the importance of preparedness for extreme heat days.
