Latest South African Weather Service (SAWS) advisories and ensemble forecasts from ECMWF and GFS models show a tight consensus for Cape Town's highest temperature on April 15 clustering at 20-21°C, fueling the near-even market-implied odds of 29.5% for 21°C and 29.0% for 20°C. Differentiating factors include model spread over afternoon boundary layer processes: stronger southerly sea breezes from the Benguela Current favor 20°C by enhancing coastal cooling, while reduced low-level cloudiness and higher insolation could push to 21°C. Autumn climatology averages 24°C highs, but current upper-level ridging is yielding to cooler mid-latitude flows. Key watch: SAWS' next forecast cycle today and airport station observations determining the official maximum.
