Latest numerical weather prediction models indicate a daily maximum temperature in Cape Town on May 18 most likely between 21°C and 22°C, driven by a transient ridge of high pressure limiting strong cold-air advection from the Southern Ocean while allowing moderate solar heating under partly cloudy skies. Ensemble guidance from the South African Weather Service and global systems shows tight clustering around these values, with historical mid-May climatology placing the long-term average maximum near 19°C. Small differences in boundary-layer moisture and wind patterns could shift the exact peak by 1°C, explaining the closely matched market-implied odds between the two leading outcomes and the rapid repricing expected with the next model cycle.
