**Forecast models for Jeddah on August 14 show maximum temperatures clustered around 39–41°C under stable high-pressure conditions typical of mid-August along the Red Sea coast.** Official guidance from sources such as the UK Met Office projects a daytime high near 41°C, while BBC and timeanddate.com indicate around 39°C, with timeanddate listing 102°F (≈39°C) and scattered clouds. These align with climatological averages of 37–38°C slightly elevated by above-normal seasonal temperatures noted in the National Center for Meteorology outlook for the Makkah region. Coastal humidity and light northerly winds moderate afternoon peaks relative to inland areas, while strong solar heating, minimal cloud cover, and the absence of significant sea breezes or dust events support readings in the upper 30s to low 40s. Model consensus remains tight because no major atmospheric disturbances are expected in the short term, though small differences in timing of any local wind shifts or boundary-layer mixing can shift the exact daily maximum by 1–2°C. Traders appear to weigh these variables, producing closely matched probabilities for 39°C, 40°C, and 41°C or higher as the primary resolution candidates. Updated model runs and official briefings in the next 24–48 hours will likely refine the outcome range.
