**Trader consensus centers on a daily maximum of 38°C in Jeddah today, reflecting official forecast guidance from the National Center of Meteorology and global models showing afternoon peaks near that threshold under mostly clear skies and moderate westerly winds.** Coastal Red Sea influences and typical October climatology—historical highs averaging 34–35°C—support this range, with limited cloud cover and low precipitation risk keeping temperatures elevated but not extreme. Current observations around 34°C mid-morning align with model runs projecting a brief peak near 38°C before evening cooling. The modest probability for 39°C or higher accounts for potential model spread or localized heating, while lower outcomes remain negligible given the established warm pattern. Final resolution hinges on official station readings by late afternoon.
