Trader sentiment centers on numerical weather prediction models projecting a Jeddah high of 41–42°C on August 2, with coastal Red Sea moderation and light northerly winds limiting further intensification amid persistent summer high pressure. Historical August climatology shows typical maxima near 38°C, yet recent model runs incorporate slightly elevated boundary-layer heat and reduced marine influence that support the market-implied tilt toward the upper end of that range. Differentiation between 41°C and 42°C hinges on small uncertainties in daytime wind speed, humidity profiles, and exact timing of peak insolation, while lower-probability outcomes above 43°C would require stronger offshore flow or delayed sea-breeze onset not currently favored by consensus guidance. Updated regional forecasts from agencies such as the National Center of Meteorology remain the key near-term catalyst.
