Trader consensus on Sao Paulo's highest temperature March 25 heavily favors 30°C (39%) and 29°C (37.5%), reflecting ensemble weather models like GFS and ECMWF projecting peaks near 29.5°C amid mild autumn conditions. Differentiating factors include urban heat island effects in the densely built city boosting readings by 1-2°C above rural areas, light southerly winds from the Atlantic limiting sea breeze moderation, and scattered afternoon clouds capping insolation at 80-90% of potential. INMET forecasts align with this tight range, with historical March maxima averaging 28.5°C but recent dry spells enabling slight exceedances. Model uncertainty of ±1°C, from divergent boundary layer simulations, keeps 31°C viable at 14% amid low precipitation odds.

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.
