Recent forecast model consensus from sources including the Met Office points to daytime maxima of 38–40°C in Jeddah on August 19, driven by persistent high-pressure patterns, clear skies, and moderate northerly winds off the Red Sea that limit extreme heat while sustaining typical summer humidity levels around 50–70%. Ensemble spreads and slight differences in boundary-layer mixing create the tight clustering of market-implied odds around 37–40°C rather than a single dominant outcome. Historical August averages near 37–39°C provide additional context, with no major synoptic shifts expected before resolution. Updated runs on August 18 will further narrow uncertainty in peak readings.
