Recent seasonal outlooks from Saudi Arabia’s National Center for Meteorology indicate temperatures running 1–1.6 °C above the long-term August average across the western region, driven by elevated Red Sea sea-surface temperatures and persistent high-pressure patterns that limit cloud cover and rainfall. Short-range model guidance for 26 August shows daytime maxima clustered between 36 °C and 40 °C, with the precise peak hinging on local wind shifts and the timing of any diurnal heating spike. These factors create the tight market spread between the 38 °C and 39 °C outcomes, as traders weigh the likelihood of a modest exceedance versus stabilization near the climatological 37–38 °C envelope. Updated model runs and official Saudi Meteorological bulletins over the next 48 hours will refine the range.
