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 4 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.
Market-implied odds for Cape Town’s September 4 maximum temperature cluster around 19–21 °C because short-range numerical weather prediction models from the South African Weather Service and international centers converge on a peak near 20 °C. A cold front and associated cut-off low cleared the region on September 3, leaving a strong, dry southeasterly flow that favors clear skies and efficient daytime heating without significant cloud cover or moisture. Ensemble guidance shows limited spread, with afternoon temperatures most likely reaching 19–20 °C under windy conditions that limit further warming. Trader positioning therefore reflects the high-confidence 24-hour forecast, with resolution depending on official maximum readings recorded at the primary observing site.
