Latest forecast model ensembles from INMET, ECMWF, and GFS converge on a high-pressure ridge over southeast Brazil, fostering clear skies and subsidence that promote daytime heating in São Paulo, with peak implied probabilities clustered tightly around 30–31°C due to radiative warming and low soil moisture from recent dry spells. Urban heat island effects in the city amplify temperatures by 2–3°C above rural areas, differentiating outcomes from cooler 28–29°C scenarios that would require unexpected afternoon cloud cover or sea breeze incursions. Current trader consensus reflects this narrow uncertainty band, as yesterday's model runs showed minimal shifts despite slight cooling signals; INMET's afternoon update and airport observations on March 28 will sharpen resolution, with historical March maxima averaging 28°C but prone to 32°C+ outliers in similar synoptic patterns.

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.
