Forecast models from agencies like the South African Weather Service and global ensembles point to a minimum temperature near 15–16°C in Cape Town on September 23, driven by persistent cloud cover that limits nocturnal radiative cooling, moderate southerly to southwesterly winds, and a mild maritime air mass influenced by the Benguela Current. Historical September averages hover around 10°C, but recent above-normal warmth has shifted the distribution, with trader consensus reflecting model consensus on lows in the mid-teens while allowing for variability from localized urban heat effects or slight shifts in wind patterns. Upcoming evening observations and final model runs before midnight will refine resolution thresholds around these values.

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 23 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.Forecast models from agencies like the South African Weather Service and global ensembles point to a minimum temperature near 15–16°C in Cape Town on September 23, driven by persistent cloud cover that limits nocturnal radiative cooling, moderate southerly to southwesterly winds, and a mild maritime air mass influenced by the Benguela Current.
