Current forecasts for Jeddah on August 22 point to peak daytime highs of 38–45 °C under persistent subtropical high pressure, clear skies, and light northwesterly flow off the Red Sea. Sea-surface temperatures near 31 °C sustain elevated humidity that limits overnight cooling while daytime solar heating remains intense. Model consensus shows little deviation from the long-term August climatology of 37–39 °C, with only modest variability tied to local wind shifts or thin cloud bands. Traders therefore focus on whether any short-term model run or official National Center for Meteorology update will push the observed maximum above or below the typical range before the 24-hour verification window closes.
