This market will resolve to the temperature range that contains the highest temperature recorded at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 3 Apr '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 Sao Paulo-Guarulhos International Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/br/guarulhos/SBGR. 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 has locked in 100% implied probability for a highest temperature of exactly 30°C in São Paulo on April 3, 2026, driven by preliminary observational data from the resolution source—Sao Paulo-Guarulhos International Airport (SBGR) station via Weather Underground—confirming this peak amid partly cloudy skies and isolated afternoon showers. Forecasts from INMET and the city's Centro de Gerenciamento de Emergências Climáticas (CGE) had projected highs near 28–30°C under typical autumn anticyclonic conditions with moderate humidity, aligning with historical April averages of 26–28°C but slightly elevated due to light southerly winds limiting cooling. Realistic challenges would require rare post-processing revisions to SBGR records or discrepancies in automated sensor data, though model consensus and real-time reports provide strong evidentiary support for this outcome.
