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 7 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.
Traders are pricing the highest temperature in Cape Town on September 7 near 27–28 °C because current high-pressure conditions and clear skies favor strong daytime solar heating under light southwesterly winds. Recent observations show daytime maxima already reaching 25–26 °C in early September, well above the seasonal average of roughly 18–20 °C, with minimal cloud cover and low humidity enhancing surface warming. Official forecasts from sources such as the South African Weather Service and global models converge on afternoon peaks of 24–29 °C, with small differences arising from variations in boundary-layer mixing and exact wind speeds that could either cap or boost the maximum by 1–2 °C. With resolution occurring within 24 hours, updated model runs and real-time observations will determine whether the market’s tight clustering around 27–28 °C holds or shifts with any last-minute changes in insolation or advection.
