Trader consensus for Denver's August 13 maximum temperature centers on 80–83°F, reflecting model guidance from NOAA and NWS showing a moderating air mass after early-August heat spikes exceeding 100°F. Key variables include the position of an approaching trough, afternoon thunderstorm development that can cap daytime highs, and surface dewpoint trends influencing boundary-layer mixing. Ensemble spreads in guidance create genuine uncertainty around exact peaks, with slight differences in timing or coverage of clouds and convection tipping outcomes between the two leading bins. Historical August averages near 87–90°F provide context, but current patterns favor below-normal readings. Updated NWS forecasts and afternoon model runs will refine these market-implied odds.
