Recent frontal systems and low-pressure development over southern Brazil have driven cooler, unstable conditions across São Paulo in early September, with observed minima near 14–16°C amid widespread rain. Official forecasts from sources including Climatempo, INMET-aligned models, and international guidance show model spread for the September 11 minimum, with some runs projecting continued northerly flow and clearing that could hold overnight lows near or above 19–20°C, while others retain cooler maritime air or lingering cloud cover supporting values at or below 15°C. This divergence in steering patterns and boundary-layer recovery underpins the near-even market split between sub-14°C and 24°C+ outcomes, with specific bins around 18–22°C reflecting residual uncertainty ahead of updated model runs and overnight observations.

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.
