The South African Weather Service (SAWS) latest forecast pins Cape Town's May 7 maximum temperature at 19°C under partly cloudy skies, aligning with the 31% market-implied probability for that outcome and trader consensus around 17–20°C amid high short-term uncertainty. This positioning stems from the past 48 hours' advisories highlighting an orange-level warning for disruptive rainfall across the Western Cape through May 7, introducing cloudy conditions and cooling influences from a passing low-pressure trough that temper highs below seasonal May averages of 19–20°C. Key variables include cloud cover variability across forecast models like ECMWF and GFS ensembles, potential berg wind warming if high pressure builds post-front, and frontal passage timing, all contributing to the tight probability spread. New SAWS updates and model runs expected daily could refine odds as resolution nears.
