Current forecasts from major meteorological models, including those aligned with the South African Weather Service, project a daytime maximum of 22°C for Cape Town on May 16 under stable high-pressure conditions and light southerly winds typical of mid-autumn. This aligns with the region's Mediterranean climate, where May averages hover near 19°C, and recent observational data show no anomalous warming from ocean or atmospheric patterns. The overwhelming market-implied odds for 22°C reflect trader consensus on these verified model runs and historical baselines, with minimal divergence in ensemble predictions. A realistic challenge would require an unexpected warm advection or localized measurement spike exceeding official thresholds at primary stations, though current data indicate low likelihood before resolution.
