Recent model runs from global ensembles reveal mixed signals for Jeddah’s July 6 maximum, with the 30% market-implied probability on 41 °C or higher reflecting persistent spread between drier continental flow favoring peaks near or above 40 °C and Red Sea moisture that could cap readings in the upper 30s. Key variables include the strength and timing of northwesterly winds modulating marine layer intrusion, afternoon cloud cover reducing insolation, and dew-point trends that influence the diurnal temperature range. Saudi Meteorological Authority short-range guidance and regional high-resolution updates expected within 48 hours will likely tighten the distribution ahead of resolution, while climatological July averages near 38 °C provide the baseline against which deviations are measured.
