Persistent late-summer heat patterns and strong southerly flow off the Gulf of Mexico are positioning Houston’s August 15 high temperature in the mid-to-upper 90s, aligning with the market’s leading 96–97 °F bin at 57.5 % implied probability. National Weather Service and AccuWeather guidance show sunny conditions, high dew points sustaining heat indices near 105 °F, and only modest sea-breeze moderation, consistent with the city’s August climatology of 93–98 °F daily maxima. Recent model runs indicate limited afternoon convection risk that could cap readings at 94–95 °F (26.5 %), while clearer skies raise modest tail odds for 98–99 °F (16 %). Normal maximum temperature for the date is 94 °F, underscoring how current atmospheric setup supports the consensus range ahead of final observations.
