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 11 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.Current numerical weather models and long-range forecasts from agencies like those informing AccuWeather and timeanddate indicate Jeddah's August 11 high will likely fall near 38–40°C, driven by persistent subtropical high pressure, Red Sea moisture, and typical mid-summer insolation in the region. Historical climatology shows August averages of 37–38°C with low rainfall, yet small day-to-day shifts in steering winds or boundary-layer humidity can differentiate outcomes by 1–2°C. With leading probabilities closely bunched, traders are weighting model consensus against observed variability in coastal Saudi summer maxima, while awaiting updated short-range guidance closer to the date.
