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 9 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 overwhelmingly favors 19°C as Cape Town's highest temperature today, backed by real-time observations at Cape Town International Airport—the market's resolution source—and South African Weather Service (SAWS) guidance showing fine but cool conditions with maximums around 19–20°C. Persistent high-level clouds, moderate southerly winds, and morning fog have suppressed solar heating, aligning with May climatological averages of 19°C highs amid an approaching cold front set to bring rain and winds from Sunday. Model ensembles confirm limited intensification potential. A challenge would require unexpected clearing and adiabatic warming to 20°C or higher in late afternoon, though evening cloud buildup makes this improbable as final hourly METAR reports finalize the peak.
