Denver, CO, July 20, 2026 —

Denver marked its first 100-degree day of 2026 on Monday, as temperatures soared to 100 degrees Fahrenheit at Denver International Airport. The milestone occurred on a day when a Heat Advisory was active for the region, signaling potentially dangerous conditions.

The National Weather Service typically issues Heat Advisories when conditions are expected to be a significant hazard to public health. Those most vulnerable to heat-related illnesses include the elderly, young children, and individuals with chronic health conditions.

During a Heat Advisory, residents are advised to take precautions such as staying hydrated, seeking air-conditioned spaces, and limiting strenuous outdoor activities. The high temperatures combined with humidity can increase the risk of heat exhaustion and heat stroke.

The specific duration and scope of the Heat Advisory were not detailed in the provided information, nor were any immediate impacts on city services or public health incidents directly attributed to the heat. Further details regarding the meteorological conditions leading to the extreme temperature and the official end of the advisory period were not immediately available.
