Current ensemble forecasts from global weather models place the highest temperature in Jeddah on September 12 most likely between 36°C and 38°C, aligning with the closely matched market-implied probabilities across those bins. In this coastal arid setting, peak values hinge on strong solar heating under mostly clear skies, light winds that limit vertical mixing, and the Red Sea's moderating sea breeze, which typically caps extremes near historical September averages of 35–37°C. Recent observations from early September show daytime maxima in the mid-to-upper 30s, while minor model disagreements center on exact peak timing and any weak moisture influences. Updated runs closer to the date will narrow the range.

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 12 Sep '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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Current ensemble forecasts from global weather models place the highest temperature in Jeddah on September 12 most likely between 36°C and 38°C, aligning with the closely matched market-implied probabilities across those bins.
