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 16 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, with 28°C and 29°C tied at 30.5% implied probability, reflects the latest INMET and CPTEC forecast models projecting a daytime high near 28°C for São Paulo on April 16 amid persistent high-pressure ridging over southeast Brazil, fostering clear skies and above-average autumn heating. Recent observations through April 15 show highs of 26-27°C under similar stable conditions, slightly warmer than the April climatological average of 25-26°C at official stations like São Paulo–Guarulhos Airport. Differentiating factors include model spread on afternoon sea-breeze intensification, which could introduce low-level clouds capping temperatures at 27°C (21.5%), versus sustained solar insolation pushing toward 29-30°C. Overnight forecast refinements from INMET will clarify steering patterns and boundary layer mixing before resolution.
