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 26 Mar '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.Official observations from Brazil's National Institute of Meteorology (INMET) and local weather stations confirm Sao Paulo's highest temperature reached exactly 30°C on March 26, anchoring trader consensus at 100% implied probability for this outcome. This aligns with typical late-summer conditions in the region, where sea breezes and urban heat effects cap maxima around 28–32°C amid moderating southerly winds and scattered clouds over the past week, per recent satellite imagery and surface data. No model forecasts or analogs suggested extremes above 32°C, with ensemble predictions converging on mild warmth. Resolution hinges on final verified readings; a challenge could arise only from post-audit data revisions at remote stations revealing overlooked peaks, though such discrepancies are rare below 0.5°C. Traders await INMET's official bulletin for closure.
