Forecasts from multiple models indicate Jeddah's overnight low on August 29 will likely fall between 28–31°C under persistent high pressure, clear skies, and moderate humidity near 50–70%, with light northerly or westerly winds limiting further cooling after a day of 36–39°C maxima. Recent August observations show temperatures running 1–2°C above the 27–29°C climatological baseline, driven by elevated sea-surface temperatures in the Red Sea and reduced nocturnal radiative cooling from high dew points. The tight clustering of implied probabilities around 29–32°C captures residual spread among ensemble members regarding exact minimum timing and any subtle cloud or wind variations that could shift the reading by 1–2°C before official station verification.
