Record-Breaking Temperatures on July 25
On July 25, multiple Colorado municipalities, including Denver, surpassed historic heat marks. Denver International Airport recorded a high of 101 °F, eclipsing the previous July 25 record of 99 °F set in 1963. The extreme reading broke a 60-year benchmark and was mirrored by other cities across the state.
Heat Advisory and Forecast
The National Weather Service (NWS) placed much of Colorado under a Heat Advisory, warning that hot and dry conditions will persist through Sunday. Forecasts call for additional temperatures of 100 °F or higher across northeast Colorado, the Boulder area, and the Denver metropolitan region. The agency advises residents to limit outdoor activities to early morning or evening hours and to stay well-hydrated.
Health Risks and Public Guidance
The NWS outlined early signs of heat-related illness—muscle cramps, dizziness, headaches, nausea, and dry, cracked lips—and more severe indicators such as red or hot skin, rapid pulse, confusion, or fainting. It stresses that severe symptoms require immediate medical attention. Public health officials recommend wearing lightweight, loose-fitting clothing and avoiding strenuous exertion during peak heat.
Pet Safety Concerns
Denver Animal Protection issued a parallel alert for animal owners, urging them never to leave pets unattended in vehicles and to be cautious when walking dogs on hot pavement, which can burn paws. The organization highlighted that pets are also vulnerable to heat-related illnesses and encouraged owners to watch for signs of distress, such as excessive panting or lethargy.
Key Data Points
- Denver temperature: 101 °F (airport reading)
- Previous July 25 record: 99 °F in 1963
- Heat Advisory effective through Sunday
- Expected 100 °F+ temperatures in northeast Colorado, Boulder, and Denver metro area
These conditions underscore a rare heat event for Colorado, prompting coordinated warnings from weather authorities and animal-care groups to protect both people and pets.
