Trader consensus on Polymarket assigns a 51.5% implied probability to a 30°C high in Jeddah today, with 31°C at 40% and 29°C at 37%, reflecting National Center for Meteorology observations of hazy skies and recent highs near 31°C over the past 48 hours. Persistent regional dust aerosols are reducing insolation—solar radiation at the surface—while northwesterly breezes at 10-20 km/h introduce cooler Red Sea-influenced air, moderating peaks below the early-April climatological average of 32°C. AccuWeather and BBC forecasts align at 31-32°C with hazy sun and afternoon gusts, though model ensembles show slight downside risk from increased humidity. Real-time data from Jeddah stations will clarify as the afternoon peak approaches, with resolution based on official maximum readings.
