Trader consensus on Polymarket favors 29°C at 29% implied probability for São Paulo's highest temperature on April 18, closely trailed by 28°C and 30°C at 20.5% each, reflecting model spread amid dominant high-pressure systems fostering above-normal autumn warmth. INMET and Climatempo's latest forecasts project highs near 27-28°C with sunny mornings giving way to increasing clouds and 60-70% chance of isolated afternoon showers, capping solar insolation; however, recent days' observed peaks of 27-28°C under clear skies and April's +1.5°C anomaly versus historical 25°C averages suggest potential for urban heat island effects to push toward 29-30°C if convection delays. GFS and ECMWF runs show slight divergence on peak heating, with new 00Z updates expected overnight resolving near-term uncertainty in sea breeze timing and humidity.

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 18 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.
