Current forecasts from the South African Weather Service and global models indicate a maximum temperature of 18°C for Cape Town on June 6, aligning with typical mid-winter climatology where daytime highs average near this level amid south-southeasterly winds and limited cloud cover. This strong model consensus, supported by stable atmospheric conditions and historical June baselines around 16–18°C, underpins the market’s near-certain outcome. Minor deviations remain possible if an unforecasted warm advection event or measurement adjustment occurs, though such shifts are rare given the tight agreement across official guidance.
