Recent heavy September rainfall across São Paulo, already the wettest on record since 1943 with over 250 mm by mid-month, sustained high humidity and extensive cloud cover that limited nighttime radiative cooling on the 20th. Official stations recorded overnight lows near 19°C under mostly cloudy skies with light northerly winds, keeping temperatures above typical September minima around 12–14°C. Traders see near-even odds between an 18°C low and cooler outcomes because final Inmet or airport readings can vary by station and timing, while models showed minor disagreements on exact dew-point depression. Upcoming official daily summaries will clarify whether the minimum crossed below 18°C amid these moist, stable conditions.

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 20 Sep '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 for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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 heavy September rainfall across São Paulo, already the wettest on record since 1943 with over 250 mm by mid-month, sustained high humidity and extensive cloud cover that limited nighttime radiative cooling on the 20th.
