Recent National Weather Service and private model guidance points to overnight lows in the low-to-mid 60s for Denver on August 25, driven by partly cloudy skies, light winds, and limited moisture that permit moderate radiative cooling after daytime highs near 85–90 °F. Trader consensus clusters around the 62–65 °F bins because ensemble spreads reflect uncertainty in cloud cover timing and any scattered thunderstorm outflow, which can either suppress or elevate minimum temperatures by a few degrees. Historical August climatology shows typical lows near 57 °F, so current warmer guidance stems from persistent southerly flow and above-average dew points. Updated model runs and evening observations will narrow the range before the calendar day ends.
