**Trader sentiment for Jeddah’s August 16 maximum temperature centers on the 41 °C+ bin (55.5 % implied probability) because short-range forecasts and the National Center for Meteorology’s seasonal outlook both point to above-normal heat.** Historical August climatology already places average daily highs near 38–39 °C, with coastal humidity and light winds limiting overnight cooling; recent model guidance from sources such as timeanddate and BBC Weather shows 39–40 °C (104–107 °F) for the 16th, while the broader NCM assessment flags warmer-than-normal conditions persisting across Saudi Arabia through October. These factors combine to shift the distribution upward from long-term normals, elevating the chance of readings at or above 41 °C. With resolution only 48 hours away, the next official NCM forecast update and any adjustments to the regional steering pattern remain the key variables that could still alter the final observed maximum.
