Front Range Faces Rare 5-Day Heat Wave with Record-Breaking Temps

Colorado Front Range Braces for Rare Five-Day Heat Wave Nearing Record Highs

An intense stretch of heat is set to grip the Colorado Front Range from Monday through Friday, with daily high temperatures approaching 98–99°F—levels rarely sustained in Denver’s recorded weather history. According to forecasters, a five-day streak of such extreme heat has occurred only five times in 153 years.

Denver could come close to breaking longstanding heat records, especially Wednesday (record: 100°F) and Thursday (record: 99°F). While morning temperatures will provide mild relief in the 60s and occasional afternoon clouds may offer brief shade, the risk of heat-related illnesses remains high. Officials urge residents to stay hydrated, limit strenuous outdoor activities, and watch for signs of heat exhaustion.

Fire danger will also escalate on Colorado’s Western Slope due to west winds, low humidity, and already dry conditions. A Red Flag Warning is in effect Monday with gusts up to 35 mph and humidity as low as 4%. A Fire Weather Watch is already in place for Tuesday. Ongoing wildfires could grow, and any new ignitions may spread quickly in the difficult firefighting conditions.

Even along the Front Range, Monday will bring gusty winds between 10–20 mph, with potential for 45 mph bursts in the evening. A shift in the weather pattern arrives this weekend as a trough of low pressure pushes in, cooling things down and increasing the chance for isolated rain.
