Recent forecasts from multiple models indicate Sao Paulo's overnight minimum on August 22 will likely fall between 11–13°C, driven by clear skies, light southeast winds, and strong radiative cooling under a stable high-pressure system following a cooler airmass advection. Dry conditions and low humidity enhance heat loss after sunset, with the exact low hinging on subtle differences in cloud cover timing and boundary-layer wind speeds across ensemble runs. Historical August minima average near 13°C, but recent drier patterns have supported sharper drops. Traders appear to weigh these model spreads heavily, with implied probabilities clustered tightly as resolution nears and final observational data from local stations becomes available.

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 22 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.
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.Recent forecasts from multiple models indicate Sao Paulo's overnight minimum on August 22 will likely fall between 11–13°C, driven by clear skies, light southeast winds, and strong radiative cooling under a stable high-pressure system following a cooler airmass advection.
