High-pressure systems dominating southeastern Brazil are sustaining clear to partly cloudy skies and light winds over São Paulo, enabling strong daytime solar heating that positions 30–32°C as the most probable peak for August 18. Recent model consensus from INMET and international ensembles shows surface temperatures rising to these levels by afternoon under negligible precipitation risk and dry winter conditions, well above the August climatological average of 23–25°C. Stable atmospheric patterns observed in the past week have already delivered similar or slightly lower maxima, reinforcing trader focus on the narrow 30–31°C band while limiting odds for extremes outside 29–33°C. Updated forecasts and any late shifts in cloud cover or wind will be the key variables ahead of resolution.

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 18 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.
