Recent forecasts from multiple global and regional models indicate a probable daily maximum near 38–39°C in Jeddah on August 31, driven by strong solar insolation under mostly clear skies, light to moderate northwesterly winds, and high humidity that limits overnight cooling in the Red Sea coastal zone. Slight model spread arises from differences in predicted cloud cover and boundary-layer mixing, which can shift the peak by 1–2°C, explaining the closely matched market probabilities around the 38–40°C outcomes. Historical August climatology shows typical highs of 36–40°C, with local urban effects and exact station measurement (King Abdulaziz International Airport) adding resolution uncertainty ahead of final model runs.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the King Abdulaziz International Airport Station in degrees Celsius on 31 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=oejn
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent forecasts from multiple global and regional models indicate a probable daily maximum near 38–39°C in Jeddah on August 31, driven by strong solar insolation under mostly clear skies, light to moderate northwesterly winds, and high humidity that limits overnight cooling in the Red Sea coastal zone.
