Recent forecast models for Jeddah on August 31 point to a daily minimum near 29–32°C under stable summer subsidence and Red Sea maritime air, which sustains high humidity and restricts nocturnal radiative cooling. Land-sea breeze cycles, typically shifting northwest overnight, along with variable low-level cloud cover, create the narrow spread among leading market outcomes around 32–35°C. Recent August temperatures have run about 2°C above the long-term mean, with observed minima fluctuating 28–33°C amid similar conditions. Minor differences in inversion strength or wind speed could tip the exact low by 1–2°C, keeping trader-implied probabilities closely matched until updated model runs or observations clarify the overnight trend.
