Traders see elevated odds for a peak of 25°C or higher in Cape Town on August 27 because ensemble forecasts show potential for warm berg winds descending from the interior plateau, driven by a strong high-pressure ridge and favorable upper-level flow. Winter baseline highs near 18–20°C can rise sharply when northeasterly winds align with clear skies and reduced marine influence from the cold Benguela Current. Key variables include exact timing of any frontal passage, cloud cover modulating daytime heating, and model spread between GFS and ECMWF runs that currently favor warmer solutions. Lower outcomes remain possible if onshore flow strengthens or a coastal low develops, injecting cooler maritime air. Updated short-range guidance expected within 24–48 hours will likely narrow the distribution ahead of resolution.

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 27 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
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.Traders see elevated odds for a peak of 25°C or higher in Cape Town on August 27 because ensemble forecasts show potential for warm berg winds descending from the interior plateau, driven by a strong high-pressure ridge and favorable upper-level flow.
