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 21 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the King Abdulaziz International Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Official observations from King Abdulaziz International Airport (OEJN), the resolution source for Jeddah temperatures, confirm the daily maximum reached exactly 35°C on April 21, driving trader consensus to near-certainty at 100% market-implied probability. Recent METAR reports captured peak afternoon readings near 35°C under clear skies, northwest winds around 15 kt, and low humidity (20-30%), aligning with late-April climatology where highs average 34-35°C amid neutral ENSO patterns and typical Red Sea coastal moderation. Ensemble forecasts from ECMWF and GFS had projected 33-36°C, but real-time data ruled out higher thresholds. With the day concluding, only an improbable data revision from the National Center for Meteorology (NCM) could shift this, pending final daily summary.
