**Current short-term forecast models indicate a nighttime low near 15–16°C for Cape Town on September 23, driven by partly cloudy to overcast skies, light south-to-southeast winds, and possible scattered showers associated with a passing system.** This marine-influenced regime, typical of the Benguela Current and Atlantic moderation along the Cape Peninsula, limits nocturnal radiative cooling while preventing strong warming. Trader sentiment remains split between the 11°C-or-below and 21°C-or-higher outcomes because ensemble guidance shows modest spread in frontal timing and cloud cover, which can shift the minimum by several degrees. Historical September climatology features average lows near 10–11°C, so the current mild projection reflects above-normal warmth from suppressed cold-air advection. Updated model runs and official South African Weather Service guidance ahead of the 23rd will be the key near-term catalysts for any market shift.

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.
