Forecast models for Jeddah on July 27 indicate daytime maxima most likely between 36–39 °C, with coastal Red Sea humidity and variable cloud cover limiting peak heating and creating the tight clustering around 37–38 °C. Regional pressure gradients and light winds typical of the season allow modest diurnal ranges, while any increase in insolation or reduced marine layer could push readings to 40 °C or above. Historical July extremes near 40.6 °C establish the upper tail, yet current guidance shows no strong signal for exceptional warming or suppression. Traders weigh these meteorological thresholds against the narrow resolution bands, with the balanced odds reflecting genuine forecast uncertainty two days out.
