Trader consensus on Polymarket reflects the latest forecast models from sources like AccuWeather and Weather.com, projecting Jeddah's high temperature at King Abdulaziz International Airport on April 20 around 93–95°F (34–35°C), with a slight cooling trend from recent peaks of 101°F (38°C) on April 18 amid hazy sunshine and breezy conditions. The tight clustering of implied probabilities for 34°C (25.5%), 35°C (24.0%), and 36°C (22.0%) stems from model ensemble spread driven by coastal sea breeze dynamics—potentially capping peaks via afternoon onshore flow from the Red Sea—and variable haze reducing solar insolation, against a climatological late-April average high of 35°C. Upper-level subsidence from persistent Arabian high pressure favors clear skies and warmth, but new ECMWF or GFS runs expected overnight could refine land-sea thermal contrasts, tipping outcomes amid typical ±1–2°C daily uncertainty.
