Latest forecasts from the South African Weather Service (SAWS) and global models like ECMWF converge on a maximum temperature of 23-25°C for Cape Town on April 11, positioning 24°C (41.5% market-implied probability) as trader consensus amid mild autumn conditions under a subtropical high-pressure ridge. Southerly winds at 10-20 km/h and partial cloud cover moderate coastal warming, with morning temperatures around 18-20°C rising to peak mid-afternoon before possible isolated showers. This aligns with April climatological averages of 23°C at Cape Town International Airport, reinforced by model updates over the past 24 hours showing low intensification risk. Inherent daily forecast uncertainty remains, with SAWS hourly observations determining final resolution.
