**Clear skies, moderate southeasterly winds, and high pressure are keeping overnight radiative cooling limited in Cape Town on September 18, 2026.** Official forecasts from multiple sources converge on a daily minimum near 11–12 °C (roughly 52–54 °F), consistent with the month’s climatological average low of about 10 °C but tempered by the persistent southeast flow off the cool Benguela Current. This airflow promotes mixing that prevents the sharp temperature drops seen under calm conditions, while dry air (dew points in the single digits Celsius) allows efficient heat loss after sunset yet is offset by wind speeds of 10–20 km/h. Model runs show little disagreement, with no incoming cold front or unusual upper-level support for stronger cooling. Market-implied odds clustered tightly around 9–11 °C reflect residual uncertainty over exact station readings—urban heat-island effects, slight variations in wind gusts, or the precise timing of the minimum can shift the recorded low by 1–2 °C. With resolution imminent via official observations, traders are weighting the latest model guidance and historical analogs for similar high-pressure spring setups.

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 18 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.**Clear skies, moderate southeasterly winds, and high pressure are keeping overnight radiative cooling limited in Cape Town on September 18, 2026.** Official forecasts from multiple sources converge on a daily minimum near 11–12 °C (roughly 52–54 °F), consistent with the month’s climatological average low of about 10 °C but tempered by the persistent southeast flow off the cool Benguela Current.
