Recent forecasts from meteorological agencies project a daytime high in Jeddah around 39–41°C on August 18, creating tight trader consensus between the 39°C and 40°C+ outcomes amid typical summer conditions. August climatology shows average highs near 38–39°C, modulated by Red Sea humidity, coastal winds, and clear skies that limit cloud cooling but allow rapid afternoon peaks. Official resolution hinges on precise station measurements, where minor differences in wind timing or local heat islands can shift the recorded maximum by 1–2°C. With no major weather systems approaching, sentiment reflects model consensus on stable high pressure and very low precipitation chances through the resolution window.
