Highest temperature in Atlanta on August 27?

Platform comparison

Market context

Atlanta’s late-August heat profile points to a fairly narrow band: the National Weather Service climate normal for the station puts average maximum temperatures around 85.8°F, while daily highs in August commonly sit in the upper 80s to low 90s. The NOAA climate record also shows 8/27 has historically produced a spread of outcomes rather than a single fixed number, with the station’s August record high at 104°F and the historical highest value for 27 August listed at 95°F in the climate summary.

For the current setup, the live forecast support leans warm rather than extreme, with recent outlooks for Hartsfield-Jackson calling for highs in the lower 90s and some thunderstorm risk, though cloud cover and showers can cap the day’s peak if they arrive early enough. That matters because this market resolves on the single highest NOAA hourly “Temp” reading at KATL, so the key swing factor is whether convection, cloud build-out, or a late-afternoon cool-down prevents the airport from touching the low-90s range implied by the forecast. If the hourly data were to be incomplete, the market rules fall back to Weather Underground, which makes the final print more about the observed station series than the headline forecast.

UK Frequently Asked Questions

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.
