Short-term forecast guidance and climatological norms position Jeddah’s June 16 peak near 37–39°C, with market-implied probabilities clustered tightly around these outcomes. The city’s Red Sea coastal setting produces hot, humid conditions where average June highs reach about 37°C, driven by intense solar insolation, clear skies, and light onshore winds that limit extreme spikes while sustaining high humidity. Recent early-June observations of 35–40°C under stable high pressure reinforce this range, with minor day-to-day differences arising from small variations in wind speed and boundary-layer mixing. Updated model runs in the next 48 hours will likely refine the exact maximum, as steering patterns and any increase in cloud cover remain the key variables within the narrow uncertainty band.
