Current forecasts for Jeddah on August 31 point to nighttime lows near 29–32°C, driven by the Red Sea's persistent marine influence that sustains high humidity (often 60–80%) and restricts radiative cooling after sunset. This produces a modest diurnal range typical of the region's late-summer conditions, with recent model runs showing stable high pressure and light winds limiting further drops. The closely matched market odds around 32°C versus 35°C+ reflect uncertainty over exact minimum thresholds, where clearer skies or slightly stronger onshore flow could allow modest additional cooling toward 28–30°C, while increased cloud cover or higher dew points would favor warmer readings. Historical August baselines near 27–28°C underscore how current warmth elevates the chance of outcomes above 30°C.
