Current forecast models from sources including WeatherBug and The Weather Outlook project a September 1 high near 18–19 °C for Cape Town, supported by mild southerly flow, light winds, and limited cloud cover under a stable Atlantic high-pressure regime typical of early spring. This aligns with the market’s heaviest weighting on 19 °C (44 %) and 18 °C (32.5 %), while the low probability assigned to 20 °C or warmer reflects the absence of stronger warming signals in recent model runs. Historical September averages near 18 °C provide additional context, with minimal deviation expected absent a late shift in steering patterns or frontal passage. Updated NHC-style guidance or local SAWS briefings over the next 48 hours remain the key variables that could adjust these implied probabilities.

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 1 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.
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.Current forecast models from sources including WeatherBug and The Weather Outlook project a September 1 high near 18–19 °C for Cape Town, supported by mild southerly flow, light winds, and limited cloud cover under a stable Atlantic high-pressure regime typical of early spring.
