Forecast models from sources including NOAA-aligned outlooks and regional analyses indicate a maximum near 36–37°C for Jeddah on September 10, driven by persistent high pressure, light westerly winds off the Red Sea, and typical late-summer humidity levels that limit overnight cooling. Recent observations show daily highs declining from 38°C early in the month to 36–37°C, consistent with seasonal norms and the absence of stronger onshore flow or cloud cover that could alter peak readings. Trader consensus remains closely split between 37°C and 38°C because small variations in afternoon sea-breeze timing or localized heating can shift the exact maximum by 1°C, with final resolution depending on official station data from Jeddah King Abdulaziz International Airport.

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.
