Trader consensus at 100% implied probability for a 25°C daily maximum in Cape Town on September 5, 2026, reflects consistent official and model guidance showing clear skies, light to moderate southeasterly winds, and afternoon warming under stable high-pressure conditions typical of early spring. Real-time observations and GFS-based forecasts indicate a peak near 24–25°C, aligning with seasonal baselines while exceeding recent daily maxima around 20–21°C earlier in the month. This outcome draws support from minimal cloud cover and dry air masses that allow efficient solar heating. Scenarios that could realistically alter the result include unexpected afternoon cloud buildup or stronger winds reducing insolation, potentially capping the high below the threshold, though current data show low probability of such shifts before resolution.

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.
