Current ensemble forecasts from the South African Weather Service and global models position a 18–19 °C maximum as the most probable outcome for Cape Town on September 1, reflecting typical early-spring conditions moderated by the Benguela Current and a stable high-pressure ridge. Historical September maxima average 18–19 °C, with day-to-day variability driven by onshore flow or brief warm advection; recent model runs show limited spread around these values and no strong signals for anomalous warming or cooling. Updated short-range guidance and local observations through the final 48 hours will refine the precise peak before market 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
