Recent forecasts and Saudi Arabia’s hotter-than-normal summer outlook are anchoring trader sentiment around 42–43 °C for Jeddah’s August 1 maximum. The National Center for Meteorology anticipates temperatures 1–2 °C above the long-term August average of roughly 38–39 °C, driven by persistent high pressure, reduced Red Sea breeze, and elevated humidity that limits nocturnal cooling. Short-range models show modest day-to-day variability tied to steering flow and possible dust loading, creating the tight clustering of probabilities between 41 °C and 44 °C. With resolution only 48 hours away, the next official guidance updates will likely tighten or shift these implied odds as new observational data refine the thermal profile.
