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 3 May '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Cape Town International Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized. 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. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket reflects deep uncertainty in Cape Town's May 3 highest temperature, with 50% implied probabilities for ≤17°C and ≥27°C amid forecasts clustering near 20°C from SAWS and models like AccuWeather (68°F/20°C high, variable clouds). Recent passage of a late-April cold front suppressed regional highs below seasonal norms (average May maximum ~20°C), fostering bets on persistent cool southerlies, cloud cover, and showers keeping temps low. Countering this, some ensemble spreads in GFS/ECMWF highlight potential for rapid warming via berg winds—hot, dry föhn flows off the mountains under high-pressure ridging—driving the hot outlier. Resolution hinges on official SAWS station data; watch daily forecast updates for model convergence.
