Recent forecasts from sources including BBC Weather and numerical models indicate a peak temperature near 36–37°C for Jeddah on June 25, aligning with the closely bunched market-implied odds around those bins. Coastal sea breezes from the Red Sea and moderate humidity typically cap daytime maxima below inland Saudi values, while clear skies and high pressure promote strong solar heating during peak insolation hours. Minor model differences in predicted wind speed, cloud cover, or boundary-layer mixing create the tight spread between 36°C and 38°C outcomes. Official readings at King Abdulaziz International Airport will resolve the market; updated global model runs over the next 48 hours remain the key near-term catalyst.
