Persistent cloud cover and widespread rainfall forecast for September 14 are suppressing daytime heating in São Paulo, with official models showing highs most likely between 16–18°C amid a cool anomaly and southeasterly flow. High humidity, low insolation, and a frontal boundary reduce the potential for warmer outcomes above 19°C, while the risk of brief clearing keeps lower readings like 15°C or below in play. Trader consensus at 34% for 17°C reflects this narrow range, with model updates from agencies like INMET expected to refine the exact maximum before resolution.

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 14 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 and widespread rainfall forecast for September 14 are suppressing daytime heating in São Paulo, with official models showing highs most likely between 16–18°C amid a cool anomaly and southeasterly flow.
