Forecast models from the National Weather Service and private sources converge on a high near 88°F for Denver on August 25, reflecting a partly cloudy setup with modest afternoon convection possible. Light northeast winds and limited moisture support gradual warming from overnight lows in the mid-60s, while scattered thunderstorms—driven by daytime heating and orographic lift from the Front Range—could briefly reduce solar insolation and cap the peak if they develop earlier than expected. This uncertainty between 86–89°F brackets the market’s leading probabilities, consistent with the 1991–2020 climatological average high of 85.9°F and recent model runs showing minimal deviation.
