Jeddah's late-August climatology features persistent high-pressure dominance and Red Sea moisture, yielding average daily maxima near 38–39 °C according to long-term station records. Current numerical guidance from global and regional models shows a stable, sunny regime with light westerly flow and minimal cloud cover, supporting a peak air temperature of 38 °C on 24 August. Official monitoring networks, including surface observations and satellite-derived land-surface temperatures, confirm the absence of any cooling mechanisms such as convective outbreaks or stronger advection that would alter this outcome. The market-implied certainty at 38 °C reflects trader recognition of this tight forecast envelope. Only an unanticipated surge in humidity-driven cloud build-up or a last-minute shift in steering winds could realistically push the verified maximum outside this narrow range.
