Recent forecasts from multiple models indicate sunny, stable high-pressure conditions over Cape Town for September 8, with afternoon highs most likely reaching 24–28°C under light northwest to southwest winds and minimal cloud cover. This setup favors strong daytime heating from spring insolation, though slight variations in wind direction and boundary-layer moisture create the tight clustering of market-implied probabilities around 27–29°C. Current observations show a warm spell with similar maxima on preceding days before a cooler front arrives on the 9th. Updated model runs and official South African Weather Service guidance expected in the next 24–48 hours will refine the precise peak.

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.
