**Forecast models from GFS and regional guidance indicate the overnight minimum in Cape Town will reach approximately 10°C under partly cloudy skies and light southerly to southwesterly winds that permit moderate radiative cooling.** This aligns with observed evening temperatures near 14–15°C and typical springtime nocturnal drops of 4–6°C in the region. Historical October minima average around 11–12°C, providing context for the current positioning. The 95% market-implied probability for 10°C reflects strong model consensus, though slight variations in cloud cover, wind speed, or exact station measurement could push the recorded low to 9°C or hold it at 11°C. Updated model runs and official South African Weather Service observations will determine final resolution.
