Highest temperature in Atlanta on August 5?

Platform comparison

Market context

Atlanta’s airport high on 5 August settled in the **mid-to-upper 80s Fahrenheit**, not remotely near the 0% YES implied by the market, with forecast products and the trading board both pointing to a daily maximum around 84–87°F rather than anything outside that band.[1][2][3] For a temperature market keyed to Hartsfield-Jackson, the important number is the single highest reading at the station over the full day, so the outcome depends on whether the afternoon peak briefly tags the upper 80s or stalls in the mid-80s.[3][11]

Historically, early August in Atlanta is firmly a heat month, with average highs around the mid-80s and frequent excursions into the 90s when the air mass is dry enough.[2][11][12] That makes a low-ceiling outcome such as 75°F or below structurally unlikely unless rain or persistent cloud cover suppresses the diurnal rise; recent climatology also shows Atlanta has recorded much hotter days in August, including 98°F on 4 August 2006 and 99°F on 26 August 2023, which frames how wide the upside can be when the pattern turns favourable.[12]

The main catalysts are the day-of forecast updates, especially any shift in thunderstorm coverage, cloud depth, or rain timing around the afternoon heat peak, because those are the variables most likely to nudge the station reading across a one-degree bracket.[7][8][17] Traders should watch National Weather Service and local broadcast updates into the morning and early afternoon, since short-term changes in convective timing can move the final high by several degrees even when the broader August pattern remains hot.[8][14][17]
