Forecast models for Jeddah on August 23 cluster around a peak near 40°C, driven by typical late-summer Red Sea coastal conditions including intense solar heating, light northwesterly winds, high humidity, and negligible precipitation. August climatology shows average daily maxima of 38–39°C, with historical records frequently reaching the low 40s under similar synoptic patterns. Current guidance from agencies such as the National Center for Meteorology indicates above-normal temperatures across the region without major deviations or cooling influences like stronger onshore flow. Trader consensus at 100% implied probability for the 40°C outcome reflects this narrow, well-supported range, though minor shifts in boundary-layer mixing or localized sea-breeze effects could still nudge the official high into adjacent bins.

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 23 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.
