**Trader consensus heavily favors a 14°C high for São Paulo on September 7, with market-implied probability at 99.7%.** This positioning reflects official meteorological observations and model consensus pointing to a daily maximum of exactly 14°C, driven by a polar air mass and associated cloud cover that suppressed typical early-spring warming. Current surface analyses show southeasterly flow, high humidity, and widespread stratus limiting solar heating, consistent with readings hovering near 12–14°C during peak afternoon hours. Historical September averages near 23°C underscore the anomaly. While measurement revisions from primary stations or microscale variations could theoretically alter the recorded high, the tight clustering of forecast guidance and real-time data makes such shifts unlikely 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 7 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.**Trader consensus heavily favors a 14°C high for São Paulo on September 7, with market-implied probability at 99.7%.** This positioning reflects official meteorological observations and model consensus pointing to a daily maximum of exactly 14°C, driven by a polar air mass and associated cloud cover that suppressed typical early-spring warming.
