**Trader sentiment for the Cape Town minimum temperature on August 23 reflects moderate uncertainty around official forecasts of 11–12°C.** Multiple models, including those referenced by the South African Weather Service and international services like Time and Date and PredictWind, indicate overnight lows near 11–12°C under mostly clear to partly cloudy skies with light to moderate southerly winds. These conditions support radiational cooling but lack the strong cold-air advection seen in the mid-August cold front and cut-off low that dropped temperatures earlier in the month. Differentiation among the tightly grouped outcomes (6°C or below at 37% versus 10–13°C bands near 25–30%) stems from small variations in wind speed, cloud cover, and model spread in boundary-layer mixing—factors that can shift the nightly minimum by 2–4°C. With resolution two days away, updated SAWS guidance and ensemble runs will likely tighten the distribution as the 23rd approaches.
