Official METAR observations from King Abdulaziz International Airport (OEJN) in Jeddah confirmed a mid-afternoon peak temperature of 35°C on April 29, 2026, driving trader consensus to a near-certain 100% implied probability for this outcome on Polymarket. Hazy skies and northwest winds of 10-35 km/h, as reported by Saudi Arabia's National Center for Meteorology (NCM), capped further heating despite reduced cloud cover allowing greater solar insolation than GFS and ECMWF ensemble forecasts of 33-34°C, aligning with late-April climatological averages around 34.5°C. Finalized data from Weather Underground, the resolution source, is pending but expected to affirm this; a realistic challenge would require an improbable post-preliminary revision uncovering a 36°C reading amid evening cooling.
