Latest National Center of Meteorology observations and forecast model consensus from GFS and ECMWF ensembles position Jeddah's April 11 high temperature around 29-31°C, reflecting trader-implied probabilities with 30°C leading at 51.5%, followed closely by 29°C (38.5%) and 31°C (37.5%). Northerly winds at 15-25 km/h, hazy conditions reducing solar insolation, and coastal sea breeze moderation from the Red Sea are suppressing daytime heating below the April climatological average of 34-35°C. These factors stem from a persistent high-pressure ridge over the Arabian Peninsula, with recent 24-hour data showing morning lows near 22°C and gradual warm-up. Real-time monitoring through afternoon hours and evening NCM updates could refine the peak, as model runs exhibit 1-2°C spread in peak temperature projections.
