Forecast model ensembles show substantial uncertainty in Cape Town's overnight minimum for September 15, with no single temperature bin commanding majority implied probability. Spring transition brings variable cold fronts and ridging high-pressure systems that can produce sharp nocturnal cooling under clear skies or milder conditions with increased cloud cover and northerly flow. Official guidance from the South African Weather Service and global models like GFS and ECMWF will update overnight, highlighting how small shifts in boundary-layer moisture or wind speed can swing the minimum by several degrees. Traders are pricing this dispersion as the market awaits the next model cycle and any late-day observational adjustments.

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.
