Recent forecast guidance for Cape Town places the June 16 maximum near the long-term June average of 17–18 °C, with ensemble runs from regional and global models clustering tightly between 18 °C and 19 °C. A cold front that crossed the Western Cape earlier in the week has largely cleared, leaving light south-easterly flow and limited cloud cover that supports modest daytime warming. Minor differences in predicted wind strength and residual moisture explain the near-even market split between the 18 °C and 19 °C outcomes; stronger onshore flow or lingering marine layer would cap the high at 18 °C, while clearer skies and slightly reduced wind would allow a brief push to 19 °C. Updated South African Weather Service model runs and satellite observations over the next 48 hours will be the key data points traders monitor before resolution.
