Recent forecast models from AccuWeather and timeanddate indicate São Paulo highs near 28–31°C on August 17 under mostly clear to partly cloudy skies, driving trader consensus toward the 29–31°C outcomes. In the Southern Hemisphere winter, São Paulo typically sees daytime maxima around 23–25°C, but current steering patterns and reduced cloud cover support modest warming above seasonal norms. Official monitoring shows stable high-pressure influence with low precipitation risk, limiting cooling from evaporation or storms. Model runs emphasize these conditions as the key variables, with any late shifts in upper-level flow or increased moisture potentially narrowing the range toward 28°C or pushing isolated readings to 32°C. Market-implied odds reflect aggregated assessment of these near-term meteorological signals ahead of final observational data.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
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 17 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Sao Paulo-Guarulhos International Airport Station, 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 until the first data point for the following date has been published on the resolution source.
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.
