Ensemble forecasts from leading models like ECMWF and GFS drive trader consensus toward a Sao Paulo high of 30°C or 31°C on March 27, with implied probabilities tightly split at 31% and 30.5%, reflecting model spread amid lingering summer heat. Recent INMET updates indicate partly cloudy skies and highs near 30°C, tempered by afternoon sea breezes that cap peaks below 32°C in recent analogs. Differentiating factors include urban heat island amplification pushing toward 31°C versus potential convective showers favoring 29-30°C; historical March maxima average 28-29°C but recent El Niño warmth elevates baselines. Traders eye tomorrow's 12Z runs for resolution shifts, as small variances in boundary layer moisture decide the razor-thin edge.

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.
