**Market-implied odds cluster tightly around 38–41°C for Jeddah’s August 31 maximum, reflecting modest forecast spread in the final 48 hours.** Typical late-August conditions feature strong solar heating under mostly clear skies in the city’s hot arid climate, with historical averages near 36–38°C and occasional peaks above 40°C when winds remain light and humidity from the Red Sea stays elevated. Recent model guidance shows afternoon highs ranging 37–42°C depending on the exact timing and strength of northwesterly flows that can enhance or suppress the sea-breeze cooling effect, plus minor variations in low-level cloud cover that alter surface radiative heating. With resolution hinging on the official daily maximum recorded at local stations, traders are weighting the latest high-resolution runs and ensemble spreads that will update through the weekend.

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.**Market-implied odds cluster tightly around 38–41°C for Jeddah’s August 31 maximum, reflecting modest forecast spread in the final 48 hours.** Typical late-August conditions feature strong solar heating under mostly clear skies in the city’s hot arid climate, with historical averages near 36–38°C and occasional peaks above 40°C when winds remain light and humidity from the Red Sea stays elevated.
