Latest forecasts from INMET and global ensembles point to a Sao Paulo minimum near 12–13 °C on August 21, driven by a stable high-pressure system delivering clear, dry winter air that favors strong nocturnal radiative cooling. With low humidity and light winds, surface heat escapes efficiently after sunset, while the preceding days’ mild advection has kept daytime maxima near 26 °C without introducing warmer boundary-layer air. Ensemble spread centers on 11–14 °C because small differences in residual cloud cover or katabatic drainage from the Serra do Mar can shift the overnight low by 1–2 °C. Historical August climatology shows similar minima under comparable anticyclonic regimes, supporting the tight clustering of market-implied probabilities around these thresholds.

This market will resolve based on the lowest 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 lowest temperature recorded at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.
