Trader consensus on Polymarket reflects near-certainty that Cape Town International Airport recorded a maximum temperature of 18°C on May 13, 2026, aligned with the South African Weather Service (SAWS) forecast of 17–18°C amid persistent cloudy skies and light south-westerly winds. Following disruptive heavy rainfall and gale-force winds from a cold front on May 11–12, overcast conditions have suppressed solar heating, with current observations hovering near 17°C and minimal diurnal warming potential left in the short autumn day. Model consensus supports this cap, consistent with Western Cape climatology during post-frontal stabilization. A late clearing could marginally challenge this via brief insolation, though steering patterns favor continued cloudiness. SAWS final daily report expected soon after midnight.
