**Clear skies, moderate south-southeasterly winds, and stable high-pressure conditions are supporting overnight radiative cooling in Cape Town’s Mediterranean climate, positioning the minimum temperature near 13–16 °C (55–61 °F) on 20 September 2026.** Multiple forecast models (GFS-based and others) converge on a low around 14–16 °C, consistent with recent September observations where overnight minima have ranged from roughly 10–14 °C amid above-average warmth earlier in the month. The absence of incoming cold fronts or strong northerly flow limits deeper cooling, while clear conditions and light winds favor the upper end of the cooler range. Trader consensus reflected in the market-implied odds—led by 13 °C at 55 %—aligns with this model agreement and historical spring baselines, though slight variations in wind strength or cloud cover could still shift the exact reading by 1–2 °C. Updated official observations from stations such as Cape Town International will determine final resolution.

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.**Clear skies, moderate south-southeasterly winds, and stable high-pressure conditions are supporting overnight radiative cooling in Cape Town’s Mediterranean climate, positioning the minimum temperature near 13–16 °C (55–61 °F) on 20 September 2026.**
