Trader consensus for a 39°C high in Jeddah on August 13 reflects convergent numerical weather model guidance and observational trends from the Saudi Meteorological Authority and international centers, showing peak temperatures aligned with August climatology of 37–40°C under persistent subtropical high pressure, clear skies, and Red Sea humidity. Recent days have featured observed maxima near 36–38°C with strong solar heating, supporting the implied probability near certainty. Minor deviations remain possible from localized sea-breeze timing or brief cloud build-up, yet these factors rarely shift the daily maximum by more than 1–2°C in this arid coastal setting.

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.Trader consensus for a 39°C high in Jeddah on August 13 reflects convergent numerical weather model guidance and observational trends from the Saudi Meteorological Authority and international centers, showing peak temperatures aligned with August climatology of 37–40°C under persistent subtropical high pressure, clear skies, and Red Sea humidity.
