**Above-average summer heat across Saudi Arabia, including a +1.2°C anomaly forecast by the National Center for Meteorology for August 2026, underpins the market's tilt toward 41°C or higher (51.5% implied probability) for Jeddah's daily maximum on August 13.** Historical August highs average 38–39°C, but recent observations and short-range model guidance show peaks frequently reaching 40–43°C amid persistent hot, humid Red Sea air masses and strong solar heating. With the date only two days ahead, ensemble forecasts indicate limited cooling, keeping 40–41°C+ outcomes dominant while lower bins (below 39°C) reflect only modest downside risk from localized cloud cover or wind shifts. Traders are weighting the established heat dome and lack of significant relief in the latest runs.

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 13 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.
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.**Above-average summer heat across Saudi Arabia, including a +1.2°C anomaly forecast by the National Center for Meteorology for August 2026, underpins the market's tilt toward 41°C or higher (51.5% implied probability) for Jeddah's daily maximum on August 13.** Historical August highs average 38–39°C, but recent observations and short-range model guidance show peaks frequently reaching 40–43°C amid persistent hot, humid Red Sea air masses and strong solar heating.
