Forecast models indicate a high-pressure system bringing clear skies and light southerly winds to Cape Town on August 30, favoring radiative cooling overnight that could push the minimum into the 7–12 °C range. The closely bunched market odds around 10–11 °C reflect this typical winter nocturnal drop under dry conditions, while the notable 16 °C-or-higher share accounts for uncertainty in daytime mixing or slight cloud cover that might limit cooling. Official guidance from sources like the Met Office highlights a possible 7 °C low under clear conditions, whereas ensemble spreads show 10–12 °C more commonly; traders weigh these against climatological August minima near 10 °C and the absence of approaching fronts that would otherwise moderate temperatures.

The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=fact
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.
