Recent cold fronts sweeping across the Western Cape, as reported by the South African Weather Service and local forecasters like Vox Weather, have sharply lowered maximum temperature projections for Cape Town on April 18, shifting trader consensus toward the mid-teens Celsius despite April climatological highs averaging 22-23°C. Southerly winds, persistent cloud cover, and isolated showers—evident in the latest GFS and ECMWF model runs—are capping daytime heating, with ensemble spreads showing peaks between 15-19°C explaining the tight market-implied odds (16°C at 32%, flanked by 18°C at 23.5% and others near 20%). Inherent short-range forecast uncertainty persists, but updated model outputs expected April 17 will likely narrow differentiation ahead of resolution based on official observations.
