Trader consensus on Polymarket reflects the tight clustering of INMET and Climatempo forecasts projecting São Paulo's highest temperature on April 16 at 28–29°C under partly cloudy skies with morning fog and no precipitation, following recent observations of 25–28°C highs on April 13–15 amid mild autumn conditions. This positioning stems from a dominant subtropical high-pressure ridge suppressing rainfall and allowing solar heating, slightly above the April historical average of 25°C, amplified by urban heat island effects in the city. Differentiating factors include model ensemble spreads—GFS and ECMWF runs vary by 1–2°C due to uncertainties in sea breeze timing and afternoon cloud development—while Ventusky implies a cooler 25°C outlier. New 12z model updates overnight could shift odds as resolution nears.

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.
