Forecast models from sources like ECMWF and GFS, as reflected in Weather.com and TimeandDate projections, indicate a high near 37°C (96-99°F) for Jeddah on May 16 under sunny, hazy skies with light northwest winds, driving trader sentiment toward typical late-May seasonal norms. This follows thunderstorms and heavy rain across the Makkah region on May 12, which temporarily cooled conditions but have given way to a stabilizing high-pressure ridge promoting daytime heating over the Red Sea coastal plain. Jeddah's climatological May average high is 37°C, with low variability due to persistent subsidence and minimal cloud cover; however, short-range updates from the Saudi National Center for Meteorology could refine intensities amid inherent forecast uncertainty in diurnal maxima. Watch NCM briefings through May 15 for potential shifts.
