Trader consensus on Polymarket has locked in 37°C as the highest temperature in Jeddah on May 13 at nearly 100% implied probability, driven by confirmed surface observations from King Abdulaziz International Airport (OEJN) METAR reports showing a midday peak of 37°C under clear skies, moderate northwest winds, and typical coastal diurnal heating. Current evening readings around 28–31°C reflect cooling post-solar maximum, aligning with Jeddah's May climatology of 36–38°C highs influenced by Red Sea moderation and subtropical high pressure. Scenarios challenging this include a rare late heat burst from downslope flows or upward revision in National Center for Meteorology (NCM) city-center data, though minimal with sunset approaching and no model signals for spikes; final NCM daily summary expected overnight.
