Forecast consensus from near-term models places Jeddah’s June 13 peak in the 37–39 °C range, aligning with the market’s tight clustering around those outcomes. Persistent high pressure, clear skies, and light winds favor strong daytime heating over the Red Sea coastal plain, while moderate humidity and possible afternoon sea breezes cap extremes below inland Saudi values. Recent observations show daily maxima fluctuating between 33–37 °C, consistent with June climatology of 36 °C average highs. Minor differences among 37 °C, 38 °C, and 39 °C bins hinge on precise timing of peak insolation, wind shifts, and any thin cloud cover in the final 48-hour model runs, leaving traders sensitive to the next NHC or local meteorological updates.
