Recent forecast models from sources including the UK Met Office and BBC project daytime highs of 39–40°C for Jeddah on August 15, 2026, amid typical mid-August conditions of intense solar heating under clear skies, light winds, and high humidity from Red Sea moisture. These align with climatological peaks near 38°C averages but favor the upper end due to persistent high-pressure patterns and minimal cloud cover. Market-implied odds heavily favor 40°C or higher at 68.5% because near-term updates show no significant cooling from sea breezes or fronts, though slight downward revisions in some ensembles keep lower thresholds like 39°C viable at 16%. Updated model runs over the next 24–48 hours will likely refine resolution criteria around official maximum readings.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the King Abdulaziz International Airport Station in degrees Celsius on 15 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the King Abdulaziz International Airport Station, available here: https://www.wunderground.com/history/daily/sa/jeddah/OEJN.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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.
