Recent forecast models, including ECMWF runs, indicate Jeddah highs near 38–39°C for July 25 amid typical Red Sea coastal conditions, where high humidity from warm sea-surface temperatures (often exceeding 30°C) limits nocturnal cooling and sustains daytime heat. Subtle differences among leading outcomes hinge on steering winds, afternoon sea breezes, and any late intensification of a thermal low over the Arabian Peninsula, which could push peaks to 40°C or briefly higher. With only modest model spread and no major synoptic shifts expected in the next 48 hours, trader sentiment clusters around these values while acknowledging the inherent 1–2°C uncertainty range in short-range temperature predictions.
