Recent forecasts from numerical weather models indicate minimum temperatures in São Paulo on August 27, 2026, clustering in the mid-teens Celsius, with trader probabilities tightly bunched because subtle differences in nocturnal radiational cooling, cloud cover, and light northeasterly winds could shift the daily low by 1–2°C. Late-August conditions feature relatively dry air and moderate high pressure, limiting strong cold advection from southern fronts that typically drive deeper minima earlier in winter. Historical climatology places average August lows near 13°C, yet current model consensus and recent observations suggest limited overnight cooling potential under partly cloudy to clear skies, keeping outcomes near 15–17°C most probable while leaving room for modest revisions from updated runs.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 27 Aug '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=sbgr
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary resolution source.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °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 numerical weather models indicate minimum temperatures in São Paulo on August 27, 2026, clustering in the mid-teens Celsius, with trader probabilities tightly bunched because subtle differences in nocturnal radiational cooling, cloud cover, and light northeasterly winds could shift the daily low by 1–2°C.
