Current forecast consensus from global and regional models points to overnight lows near 11–12°C in Cape Town on September 18 under clear skies and persistent southeasterly flow. This setup favors moderate radiative cooling at night while sea breezes and wind mixing limit deeper drops below 10°C. Historical September minima average around 10°C, with recent observations showing stable high pressure suppressing cold-air advection. Trader balance between sub-7°C and 16°C+ outcomes reflects uncertainty over exact timing of wind shifts or minor model spreads in boundary-layer temperatures, with resolution hinging on official South African Weather Service minimum readings.

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.
