Trader consensus on Polymarket reflects the South African Weather Service's latest outlook for April 15 in Cape Town, forecasting partly cloudy conditions with morning fog along the coastline and isolated showers over the western parts, yielding cool-to-warm daytime highs amid autumnal cooling trends. This clusters implied probabilities tightly around 20–21°C (27–33.5%), as partial cloud cover and potential thundershowers limit peak solar heating compared to recent sunnier days like April 13–14 (forecast 21–22°C). Differentiating factors include fog dissipation timing, northerly wind persistence for slight warming versus southerly shifts cooling surfaces, and model ensemble spread from GFS/ECMWF analogs showing 1–2°C variability; fresh SAWS updates or afternoon observations could tip the balance before resolution.
