Recent forecasts for Cape Town on August 30 point to clearing skies after Saturday’s light rain, with southeasterly winds strengthening to 20–25 km/h under a building high-pressure system. This setup favors radiative cooling overnight, especially with dew points dropping to 5–7 °C, supporting minimum temperatures near 10–12 °C at official stations. Model consensus from sources such as the South African Weather Service and international guidance clusters in this range, consistent with late-August climatology where average lows hover around 10 °C but clear, windy nights can dip a degree or two lower. Trader probabilities concentrated at 10–11 °C reflect this narrow spread, tempered by uncertainty over exact wind strength and any residual cloud cover that could limit cooling.

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.
