**Traders assign 59.5% implied probability to 41°C or higher as the leading outcome for Jeddah’s August 12 maximum temperature due to persistent summer conditions along the Red Sea coast.** August typically features intense solar heating, high humidity, and light winds that limit cooling, with long-term climatological averages near 37–38°C but recent model guidance and broader 2026 heat patterns supporting elevated readings. Official forecasts from sources like AccuWeather indicate daily highs potentially reaching the low-to-mid 40s°C range amid clear skies and minimal precipitation, consistent with above-normal global temperatures observed earlier in the year. Short-term model consensus and the absence of cooling sea breezes or cloud cover keep the 41°C+ bin favored, though any shift in steering patterns or localized moisture could moderate the peak before resolution.
