**Clear, stable high-pressure conditions dominate Cape Town's weather heading into September 19, 2026, supporting a mild overnight minimum near 12–14°C.** Southeasterly winds and low cloud cover promote radiative cooling after sunset, yet the maritime influence and typical spring baseline (historical September lows averaging ~10°C) limit further drops. Recent model runs from GFS and local stations show consistent clear skies with no incoming cold fronts or significant wind shifts that would produce an anomalous chill below 10°C or push the low above 16°C. Trader sentiment remains split near 45.5% on the extremes because small variations in exact measurement timing, urban heat island effects, or minor model spread can shift the official daily minimum across the 11–14°C range, where multiple outcomes cluster at 19–22% implied probability. Updated forecasts tomorrow morning will refine the precise low before 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 19 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, stable high-pressure conditions dominate Cape Town's weather heading into September 19, 2026, supporting a mild overnight minimum near 12–14°C.**
