Trader consensus on Polymarket reflects the South African Weather Service's (SAWS) latest forecast of a 17°C maximum for Cape Town on April 17, down sharply from today's 23°C high due to an approaching cold front bringing cloudy skies, possible showers, and stronger winds across the Western Cape. This shift from seasonal norms—where April averages hover around 22°C—explains the clustering of implied probabilities above 70% for 15–18°C outcomes. Differentiating factors include forecast model spread (e.g., ECMWF vs. GFS) on cloud cover persistence and afternoon heating potential, with lingering low clouds potentially capping peaks at 15–16°C or partial clearing allowing 17–18°C. A SAWS update or real-time observations could refine this before resolution.
