**Recent forecasts for Jeddah on July 26, 2026, center on daily maximums near 38–39°C (roughly 100–102°F), aligning with the clustered market probabilities around 38–41°C.** Standard July conditions feature intense solar heating under mostly clear skies, with average highs historically near 38–39°C and occasional peaks above 40°C driven by the region's subtropical high-pressure ridge and minimal cloud cover. The Red Sea's proximity adds high humidity that can slightly suppress peak temperatures via marine influence and sea-breeze effects, while urban heat in Jeddah may locally elevate readings. Model consensus shows limited day-to-day variability expected through the weekend, with no major heatwave or anomalous wind patterns noted in current guidance. Differentiation between 38°C, 40°C, and 41°C+ outcomes hinges on small forecast uncertainties in daytime cloud fraction, wind speed (stronger onshore flow cools more), and exact timing of peak insolation. These factors create the tight spread in trader-implied odds, as even modest shifts in boundary-layer moisture or radiative heating can alter the observed maximum by 1–3°C. Updated model runs and official observations closer to the date will likely refine these probabilities further.

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 26 Jul '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.**Recent forecasts for Jeddah on July 26, 2026, center on daily maximums near 38–39°C (roughly 100–102°F), aligning with the clustered market probabilities around 38–41°C.** Standard July conditions feature intense solar heating under mostly clear skies, with average highs historically near 38–39°C and occasional peaks above 40°C driven by the region's subtropical high-pressure ridge and minimal cloud cover.
The Red Sea's proximity adds high humidity that can slightly suppress peak temperatures via marine influence and sea-breeze effects, while urban heat in Jeddah may locally elevate readings. Model consensus shows limited day-to-day variability expected through the weekend, with no major heatwave or anomalous wind patterns noted in current guidance.
Differentiation between 38°C, 40°C, and 41°C+ outcomes hinges on small forecast uncertainties in daytime cloud fraction, wind speed (stronger onshore flow cools more), and exact timing of peak insolation. These factors create the tight spread in trader-implied odds, as even modest shifts in boundary-layer moisture or radiative heating can alter the observed maximum by 1–3°C. Updated model runs and official observations closer to the date will likely refine these probabilities further.
