**Current forecasts for São Paulo on September 20, 2026, show overnight lows clustered near 18°C, driven by persistent cloud cover, light northerly winds, and scattered rain that suppress radiative cooling.** Multiple models (including GFS runs and local Brazilian guidance) indicate dew points holding around 16–18°C, which limits how far surface temperatures can fall even under overcast skies. Northerly flow advects milder air, while urban heat island effects in the metro area add a small buffer against sharper drops. The tight clustering of market-implied odds around 14–18°C reflects genuine forecast uncertainty in minimum temperature. Key variables include the exact timing and coverage of showers (which can either trap heat or enhance evaporative cooling) and any late-day clearing that would allow greater longwave radiation loss. Historical September climatology places typical minimums in the 14–16°C range, so today’s conditions sit slightly above average due to the warm advection and moisture. Traders appear to weigh the balance between stable, rainy conditions favoring readings near 18°C versus any unexpected clearing or stronger frontal passage that could push values toward 14–15°C or lower. Updated model runs and official INMET or IPMet bulletins on overnight observations will be the next key inputs as the daily minimum is finalized.

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.**Current forecasts for São Paulo on September 20, 2026, show overnight lows clustered near 18°C, driven by persistent cloud cover, light northerly winds, and scattered rain that suppress radiative cooling.** Multiple models (including GFS runs and local Brazilian guidance) indicate dew points holding around 16–18°C, which limits how far surface temperatures can fall even under overcast skies.
