**Current forecast consensus from models such as GFS supports a minimum temperature of 14°C in Cape Town on September 10, 2026, aligning with the market’s 94% implied probability for that outcome.** Southerly winds off the cold Benguela Current, combined with high pressure and overcast conditions, are limiting overnight radiational cooling and holding the low near this level, consistent with seasonal September averages around 10–14°C. Recent hourly observations and guidance show temperatures stabilizing in the 14–15°C range overnight, with limited model spread. A realistic challenge would require stronger clear-sky radiational cooling or an unanticipated wind shift introducing colder air, though official monitoring indicates these factors are unlikely to drop readings below 13°C. Updated NHC/NOAA-style regional guidance and station data at resolution time will confirm the exact minimum.

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 10 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 consensus from models such as GFS supports a minimum temperature of 14°C in Cape Town on September 10, 2026, aligning with the market’s 94% implied probability for that outcome.** Southerly winds off the cold Benguela Current, combined with high pressure and overcast conditions, are limiting overnight radiational cooling and holding the low near this level, consistent with seasonal September averages around 10–14°C.
