Trader consensus pins the highest temperature in Sao Paulo on March 24 at 30°C with 35.5% implied odds, propelled by updated INMET forecasts and GFS/ECMWF models projecting peaks of 29-31°C under high-pressure subsidence inhibiting clouds and convection. March norms hover at 27-28°C, but urban heat island amplification and fading El Niño influences have sustained above-average warmth, with recent days hitting 30-32°C amid low humidity. Minimal rain probability enhances solar insolation for radiative heating, though afternoon sea breezes may temper extremes; watch 12Z model runs for shifts in boundary layer stability affecting these clustered 28-32°C outcomes.

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.
