A cold front advancing into São Paulo on September 5 is driving the market's emphasis on 15–16°C minima, as polar maritime air behind the system lowers overnight temperatures amid widespread rain and cloud cover. Official forecasts from sources such as the Met Office and regional models indicate the front will arrive overnight or early Saturday, producing daytime highs near 21–27°C before radiative cooling under saturated conditions pushes lows into the mid-teens; some European model runs show potential for 14°C or lower if the air mass arrives stronger or winds remain light. Trader consensus on 15–16°C reflects this balance between typical September climatology (around 12°C average minimum) and the moderating influence of precipitation, while elevated odds on 12°C or below capture tail risk from faster intensification. Updated model guidance and official INMET briefings on Saturday morning will refine the exact overnight minimum.

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.
