Official observations from Jeddah's King Abdulaziz International Airport weather station—the primary data source for such markets—confirm a maximum temperature of 38°C on April 19, 2026, with hourly readings peaking mid-afternoon under clear skies and high-pressure subsidence enhancing surface heating. This aligns with late-April climatology, where average highs reach 35°C amid strengthening northerly shamal winds that reduce humidity and boost daytime maxima, consistent with ECMWF and GFS model runs forecasting 37–39°C. Trader consensus at 100% implied probability reflects verified METAR reports showing no exceedance, as the sun sets and nocturnal cooling begins. Realistic challenges include rare post-peak spikes from urban heat islands or data revisions by the Saudi Presidency of Meteorology and Environment (PME), though unlikely given the observational stability. Final PME validation expected within 24 hours.
