Traders favor 29–31°C as the lowest temperature in Jeddah on August 22 because official forecasts and model guidance show overnight minima clustered in this narrow band amid typical late-summer conditions. The Red Sea’s high humidity and moderate sea-surface temperatures limit radiative cooling after sunset, while light westerly winds and generally clear skies promote steady nocturnal temperature drops without strong advection of cooler air. Recent observations confirm daytime highs near 37–40°C and prior-night lows of 28–31°C, consistent with climatological August averages. Minor forecast spreads arise from small differences in predicted cloud cover and boundary-layer mixing, which can shift the minimum by 1–2°C. No significant synoptic changes or data revisions have altered this consensus in the past 48 hours.

This market will resolve based on the lowest 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 lowest temperature recorded at the King Abdulaziz International Airport Station in degrees Celsius on 22 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.Traders favor 29–31°C as the lowest temperature in Jeddah on August 22 because official forecasts and model guidance show overnight minima clustered in this narrow band amid typical late-summer conditions.
