Forecast consensus from multiple meteorological sources, including model outputs aligned with official agency guidance, centers the overnight minimum in Cape Town on August 30 near 10°C under clear skies and moderate southerly winds. These conditions promote steady radiational cooling without significant cold-air advection or cloud cover that would otherwise alter the profile. Historical August minima average 7–10°C, placing the current setup close to climatological norms for the date. Traders assign 94% implied probability to exactly 10°C as the lowest temperature because ensemble guidance shows limited downside risk from the prevailing high-pressure regime. A realistic shift would require a sharper drop in wind speeds or unexpected model revisions showing enhanced cooling, though surface observations through the evening continue to track the 10–11°C range.
