Traders assign near-certainty to a 38°C high in Jeddah on September 6 because official meteorological observations from the King Abdulaziz International Airport station recorded a daily maximum of exactly that value under typical late-summer Red Sea conditions. Afternoon temperatures climbed steadily from morning lows near 30°C amid light westerly winds, moderate humidity around 45-60%, and minimal cloud cover, aligning with seasonal climatology where September highs average 36-38°C. Model consensus from regional forecasts supported this range without significant deviation, and the market resolution hinges on verified station data rather than projections. A shift in recorded peak would require either an unreported measurement error or an unexpected late-day surge exceeding model guidance, scenarios considered highly improbable given the completed observation window.

The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=oejn
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
