Current forecast guidance from regional and global models points to a minimum temperature in Cape Town on September 20 most likely between 13–16 °C under clear skies and light southerly flow associated with a stable high-pressure ridge. This setup limits overnight radiative cooling while southeasterly winds earlier in the period have kept surface moisture low, producing the mild nocturnal temperatures now reflected in the market’s clustering around 14 °C and 15 °C outcomes. Historical September minima average near 12 °C, yet the current pattern shows limited potential for stronger cold-air advection or increased cloud cover that could push readings materially lower. Fresh model runs expected over the next 24–48 hours, particularly from the South African Weather Service and ECMWF, will refine the overnight low and may shift implied probabilities as the 48-hour window to resolution narrows.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Cape Town International Airport Station in degrees Celsius on 20 Sep '26.
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.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.Current forecast guidance from regional and global models points to a minimum temperature in Cape Town on September 20 most likely between 13–16 °C under clear skies and light southerly flow associated with a stable high-pressure ridge.
