Recent forecasts from the UK Met Office, ECMWF, and GFS models indicate a high-pressure ridge over the Arabian Peninsula driving clear skies and strong solar insolation for Jeddah on May 16, with midday peaks projected near 37–38°C. This setup favors surface heating along the Red Sea coast, where northwest winds of 7–15 mph and midday humidity around 17–25% provide limited moderation through sea-breeze effects. Trader sentiment clusters tightly around 36–38°C because historical mid-May climatology at King Abdulaziz International Airport averages 36°C, while minor model disagreements on exact timing of any coastal moisture or subsidence strength could easily shift the daily maximum by 1–2°C. Updated National Center for Meteorology bulletins and afternoon METAR observations will refine the final outcome.
