Current observational data and forecast consensus from agencies including the South African Weather Service point to a daily maximum of 18°C in Cape Town on September 15, driven by persistent cloud cover, moderate northwesterly winds shifting southerly, and light rain limiting daytime warming under typical early-spring conditions. Model runs align closely on this outcome, with afternoon readings expected near 17–18°C before cooling overnight. The market-implied odds reflect trader confidence in these measurements meeting the exact resolution threshold. Uncertainties remain around precise official station readings or minor forecast revisions from lingering showers, though significant deviation appears unlikely given the advanced stage of the day.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Cape Town International Airport Station in degrees Celsius on 15 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.Current observational data and forecast consensus from agencies including the South African Weather Service point to a daily maximum of 18°C in Cape Town on September 15, driven by persistent cloud cover, moderate northwesterly winds shifting southerly, and light rain limiting daytime warming under typical early-spring conditions.
