A cut-off low pressure system developing west of South Africa is driving cooler, unsettled conditions into the Western Cape, with official forecasts indicating northwest winds, showers, and a notable temperature drop for Cape Town on September 14. Model guidance from sources including the South African Weather Service points to daytime highs near 16–19°C and overnight lows around 13–15°C under persistent cloud cover and precipitation, though localized variations near the coast or higher terrain could push minima lower. This setup explains the market’s elevated implied probability on 10°C or below relative to milder outcomes, as traders weigh the system’s intensification potential against historical September minima near 10°C and the risk of forecast revisions from updated model runs.

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.
