This market will resolve to the temperature range that contains the highest temperature recorded at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 6 Apr '26. 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.Latest Climatempo and global model ensembles like GFS and ECMWF project São Paulo's highest temperature on April 6 at around 28°C, with trader-implied odds tightly clustered at 25.5% for 27°C and 24.5% for 28°C, reflecting model consensus amid partly cloudy conditions from sea breeze moisture. Differentiating factors include subtle divergences in cloud cover timing—earlier thickening could cap peaks at 27°C via reduced insolation, while delayed convection allows brief 28-29°C spikes under partial sun. Post-frontal stabilization after weekend rain favors highs 2-3°C above the 25°C April climatological average at official INMET stations, though urban heat and instability add uncertainty. Watch INMET's daily bulletin and 12z model runs for shifts ahead of resolution.
