Official observations from King Abdulaziz International Airport's weather station in Jeddah confirm the highest temperature on April 16, 2026, reached 102°F (39°C) at 11:45 a.m. local time, driving trader consensus to near-certainty on the 39°C outcome with market-implied odds at 100%. Hourly data showed rapid warming under clear skies and low-level haze, peaking midday before easing to 97°F by evening, amid low humidity around 22% that amplified heat index. This exceeded pre-event forecasts of 33–36°C, aligning with Jeddah's April climatology where highs average 34°C but variability from high-pressure systems can push extremes. Resolution hinges on these verified airport measurements; a challenge would require rare data correction for sensor error or quality control revision by the National Center for Meteorology, though unlikely post-validation.
