Recent numerical weather prediction model runs from agencies including the Saudi Meteorological Authority and global ensembles show a daytime maximum in Jeddah on October 16 most likely reaching 34–35°C under mostly clear to partly cloudy skies, light to moderate westerly winds near 10–15 km/h, and humidity around 50–60%. These conditions align with typical mid-October climatology for the Red Sea coast, where land-sea breezes and stable high pressure limit stronger heating or cooling. Minor model spread around afternoon peak temperatures supports the market’s concentration on 35°C and 34°C outcomes, while the low odds for 36°C or higher reflect limited potential for enhanced insolation or reduced cloud cover before the next forecast update.
