A cold front advancing across southern Brazil combined with a polar air mass has sharply lowered expected highs in São Paulo for September 6, positioning 15–17 °C as the market’s leading outcomes. Official guidance and ensemble models from sources including the National Meteorological Institute and European Centre for Medium-Range Weather Forecasts indicate an overcast day with widespread light rain, southeasterly winds of 20–30 km/h, and daytime maxima most likely between 13 °C and 16 °C after early-morning readings near 16 °C. This represents a 6–10 °C drop from early-September norms. Traders are assigning the highest implied probability to 16 °C, reflecting the tight clustering of recent model runs around that value while still allowing modest upside to 17 °C or downside to 15 °C depending on exact timing of the front’s passage. Updated high-resolution forecasts and surface observations issued in the next 24–48 hours will further refine resolution criteria.

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.
