Recent official observations and forecast models from agencies like INMET and international services positioned the overnight low in São Paulo near 15–16°C on September 18, driven by typical early-spring subtropical conditions with light easterly winds, high humidity, and partial cloud cover preventing stronger radiational cooling. No significant cold air advection or frontal passage occurred to push temperatures toward single digits, consistent with September climatology where minimums average around 12–14°C but recent patterns have trended milder. This consensus, reinforced by real-time station data showing the lowest readings clustered at 15–16°C, underpins the market’s strong 90% implied probability on 15°C while assigning minimal odds to colder or warmer outliers.

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 18 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 official observations and forecast models from agencies like INMET and international services positioned the overnight low in São Paulo near 15–16°C on September 18, driven by typical early-spring subtropical conditions with light easterly winds, high humidity, and partial cloud cover preventing stronger radiational cooling.
