Current forecast models from sources like the National Weather Service equivalents and global ensembles indicate a high of 20–21°C for Cape Town on August 25 under sunny, stable winter conditions driven by high pressure and light southerly flow, aligning with the market's concentration of probability around those outcomes. Historical August maxima average near 17–18°C, so any deviation depends on variables including daytime warming rates, potential berg wind influence, and minor cloud or wind shifts that could cap or boost readings by 1–2°C. With resolution hinging on official maximum observations, traders weigh model spread and the 48-hour forecast horizon, where small changes in steering patterns could favor adjacent bins like 19°C or 22°C.

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 25 Aug '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
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 like the National Weather Service equivalents and global ensembles indicate a high of 20–21°C for Cape Town on August 25 under sunny, stable winter conditions driven by high pressure and light southerly flow, aligning with the market's concentration of probability around those outcomes.
