**Trader consensus has converged on 38°C as the highest temperature recorded in Jeddah on September 18, 2026, reflecting real-time station observations and model consensus under clear, stable conditions.** Multiple forecasts from sources including PredictWind, Meteoprog, and regional analyses projected a daytime peak of 38°C amid typical late-summer Red Sea heat, with minimal cloud cover, light winds, and high humidity contributing to the maximum. Official monitoring aligns with this value, locking in the outcome as the day progressed. While measurement variations across stations or slight revisions in post-analysis data could theoretically alter the exact figure, the tight clustering of reports around 38°C and absence of conflicting observations make alternative thresholds (such as 37°C or 39°C) highly improbable.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the King Abdulaziz International Airport Station in degrees Celsius on 18 Sep '26.
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.**Trader consensus has converged on 38°C as the highest temperature recorded in Jeddah on September 18, 2026, reflecting real-time station observations and model consensus under clear, stable conditions.** Multiple forecasts from sources including PredictWind, Meteoprog, and regional analyses projected a daytime peak of 38°C amid typical late-summer Red Sea heat, with minimal cloud cover, light winds, and high humidity contributing to the maximum.
