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 25 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 assigns virtually 100% implied probability to a highest temperature of 29°C in São Paulo on April 25, driven by preliminary observational data from the resolution source—Weather Underground's records at São Paulo-Guarulhos International Airport (SBGR) station—showing peak METAR readings near 29°C under sunny skies and low humidity (30–50%). INMET and CPTEC/INPE forecasts aligned with this, projecting 28–30°C maxima amid a stable high-pressure system that elevated autumn norms (typically 25–27°C) via enhanced solar insolation but capped extremes with light winds and afternoon clouds. Realistic challenges include minor post-processing corrections to SBGR data pushing it to 30°C, though unlikely given model consensus; final daily summary expected soon.
