Recent forecasts from sources including the Met Office and timeanddate.com indicate a minimum temperature near 12°C for Cape Town on August 27, consistent with the market's closely bunched probabilities across 11–13°C. This reflects typical late-winter conditions, where average overnight lows hover around 10°C amid variable Atlantic influences, clear-sky radiative cooling, and light winds. Minor model divergences arise from uncertain cloud cover and any weak frontal passages that could suppress or enhance overnight temperature drops by 1–2°C. Traders appear to weigh historical climatology against these short-range ensemble outputs, with resolution hinging on official observations at Cape Town International Airport.

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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
