**Trader sentiment for Cape Town’s June 20 maximum temperature centers on the narrow spread between 23–26 °C, with 25 °C holding the highest implied probability at 27 %.** Cape Town’s Mediterranean winter climate features average June highs near 17–18 °C, yet mid-month forecasts indicate a transient warm anomaly driven by northwesterly flow ahead of an approaching cold front. Ensemble guidance from global models shows modest spread in the exact peak, primarily tied to differences in the timing of cloud clearance and the strength of warm-air advection off the interior plateau. Clearer skies and lighter winds would allow surface temperatures to reach the mid-20s, while greater marine influence or earlier frontal cloud would cap readings closer to 23 °C. No extreme heat event is indicated; the distribution simply reflects normal forecast uncertainty two days out, with resolution hinging on the final 24-hour model updates and official observations from the South African Weather Service network.

This market will resolve to the temperature range that contains the highest temperature recorded at the Cape Town International Airport Station in degrees Celsius on 20 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Cape Town International Airport Station, available here: https://www.wunderground.com/history/daily/za/matroosfontein/FACT.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °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 June 20 maximum temperature centers on the narrow spread between 23–26 °C, with 25 °C holding the highest implied probability at 27 %.**
