Trader consensus on São Paulo's March 26 high temperature centers around 30°C at 34.5% implied probability, driven by the latest ensemble forecasts from global models like ECMWF and GFS, which cluster at 29.5–31°C amid a persistent subtropical high-pressure ridge suppressing clouds and boosting insolation. Differentiating the tight race with 29°C (26%) and 31°C (19.5%) are micro-scale factors: potential afternoon sea-breeze incursions from the Atlantic could cap peaks at 29°C by enhancing coastal convergence, while urban heat island effects in the city core—amplified by concrete advection—favor 30–31°C, as seen in recent INMET observations. Low precipitation odds (10–20%) reduce cooling risks, with official Mirante station data set to resolve; overnight model updates may refine this spread.

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.
