**Trader sentiment for Cape Town’s September 2 maximum temperature centers on 19–20 °C (combined ~59.5 % implied probability), reflecting model consensus for a mild spring day ahead of a cooler frontal system.** Multiple forecasts from sources including the South African Weather Service, Yr, and international models project a daytime high near 18–19 °C under partly cloudy skies with southerly winds, consistent with early-September climatology (historical averages ~19–20 °C). Slight upward bias in market pricing likely stems from uncertainty in localized warming from reduced cloud cover or a brief berg-wind influence, while downside scenarios (18 °C or lower) would require stronger onshore flow or earlier frontal arrival. The close clustering of leading outcomes underscores genuine short-range forecast spread typical of transitional spring conditions, with resolution hinging on the final 24–48 hours of observational data and model runs.

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 2 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.**Trader sentiment for Cape Town’s September 2 maximum temperature centers on 19–20 °C (combined ~59.5 % implied probability), reflecting model consensus for a mild spring day ahead of a cooler frontal system.**
