**Persistent high-pressure ridging and clear skies over southeastern Brazil are positioning São Paulo for a peak temperature near 31–32°C on August 20, driving the market’s heavy weighting on those outcomes.** Dry-season conditions with humidity often dropping below 30–40% and light winds enable strong solar heating during peak insolation hours, pushing surface temperatures above the August climatological average of roughly 24–27°C. Latest model consensus from GFS and ECMWF shows minimal cloud cover and no frontal passages until after the 20th, supporting the observed recent trend of 29–31°C daily maxima. Traders are assigning over 80% combined probability to 31–32°C because these align with current forecast guidance and historical analogs for stable anticyclonic patterns, while lower outcomes would require unexpected cooling or increased moisture not indicated in the latest runs. Official monitoring from INMET and regional agencies continues to highlight the warm, dry setup through the period.

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 20 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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Persistent high-pressure ridging and clear skies over southeastern Brazil are positioning São Paulo for a peak temperature near 31–32°C on August 20, driving the market’s heavy weighting on those outcomes.**
