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 30 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.Trader consensus on Polymarket heavily favors 30°C (42.5% implied probability) as São Paulo's highest temperature today, closely trailed by 29°C (32%), reflecting the latest INMET and CPTEC forecast models projecting peak daytime heating to 30°C amid a dominant South Atlantic high-pressure ridge promoting clear skies and light winds. Overnight minimums near 20°C and rapid morning warming under strong solar insolation support this positioning, consistent with recent days' late-March warmth around 28-30°C averages but elevated by the subtropical ridge suppressing clouds. Historical data from São Paulo–Guarulhos Airport shows late-March highs typically 27-28°C, yet urban heat island effects amplify readings. Afternoon sea breeze onset or isolated cumulus could cap peaks at 29°C; real-time hourly observations from official stations will sharpen resolution as the day unfolds.
