**Persistent cloud cover, widespread rain, and southeasterly flow are suppressing daytime heating in São Paulo on September 13, 2026, keeping the maximum temperature centered near 16–17 °C.** Official and model guidance, including Met Office forecasts and local observations, show daytime peaks around 16–17 °C under overcast skies with light-to-moderate precipitation and dew points near 14 °C, limiting solar warming. This aligns with the market-implied odds favoring 17 °C (59 %) and 16 °C (24 %), as the cool, moist air mass—well below the September climatological average high of ~23 °C—has produced only modest diurnal rises. Recent hourly data confirm temperatures stabilizing in the mid-teens through midday with continued rain chances, reducing upside potential for 18 °C or higher. Traders are pricing in this stable, cooler regime while allowing limited room for slight forecast revisions or localized clearing that could push the peak marginally higher.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 13 Sep '26.
The resolution source for this market will be information from NOAA, specifically the highest 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.**Persistent cloud cover, widespread rain, and southeasterly flow are suppressing daytime heating in São Paulo on September 13, 2026, keeping the maximum temperature centered near 16–17 °C.** Official and model guidance, including Met Office forecasts and local observations, show daytime peaks around 16–17 °C under overcast skies with light-to-moderate precipitation and dew points near 14 °C, limiting solar warming.
