**Recent forecasts for Jeddah on August 28, 2026, show highs commonly projected between 36–41 °C under mostly sunny skies, light southwesterly winds, and typical August humidity levels around 45–55 %.** This range places the highest probability on outcomes at or above 38 °C, consistent with the market-implied odds. August climatology features average daily maxima near 37–38 °C in this Red Sea coastal location, driven by strong solar insolation, minimal cloud cover, and warm sea-surface temperatures that limit nocturnal cooling. Recent observations from late August indicate persistent hot conditions, with several prior days reaching 39 °C or higher and no significant synoptic features—such as troughs or increased cloudiness—expected to suppress temperatures on the 28th. Model consensus highlights low precipitation risk and stable high pressure, supporting efficient daytime heating. Variability in specific runs (some capping at 36–37 °C, others reaching 40–41 °C) reflects minor differences in boundary-layer moisture and wind speed, yet the overall pattern favors the upper end of the distribution. Updated short-range guidance released in the past 24–48 hours has reinforced this outlook, sustaining trader preference for the 38 °C+ bin while leaving room for modest downward revisions if coastal breezes strengthen.
