Official observations from Jeddah's King Abdulaziz International Airport weather station—the market's resolution source—confirm a peak temperature of 41°C reached mid-afternoon on April 17, driving trader consensus to near-certainty on that outcome, as reflected in the 100% implied probability. This aligns with high-pressure systems and clear skies fostering intense solar heating over the Red Sea coastal region, where April climatology typically sees highs around 32–35°C but allows outliers up to 40°C+ under subsidence conditions. Current evening readings show cooling below 35°C with sunset past, minimizing further escalation risks. Realistic challenges would require a post-sunset data revision or unverified outlier measurement, though standard meteorological protocols make this improbable; final National Center for Meteorology validation expected within 24 hours.
