Recent forecasts for Jeddah on August 31 indicate daytime highs centered around 37–39°C under partly cloudy skies and moderate northwest winds, supporting the tight clustering of market-implied odds near 38–40°C. Persistent Red Sea summer conditions, including high humidity near 45–55% and limited cloud cover, allow strong solar heating during peak hours, while sea breezes and regional pressure patterns moderate extremes. Model consensus shows minor variations in afternoon cloud thickness and wind speed that could shift the maximum by 1–2°C, creating the observed spread between 38°C and 40°C outcomes. Updated numerical weather predictions from agencies like the Saudi Meteorological Authority over the next 48 hours will provide the decisive observational data for resolution.

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 for Jeddah on August 31 indicate daytime highs centered around 37–39°C under partly cloudy skies and moderate northwest winds, supporting the tight clustering of market-implied odds near 38–40°C.
