Persistent cloud cover and widespread rain from an Atlantic frontal system are suppressing diurnal temperature ranges in São Paulo, keeping overnight lows near 13–15 °C and daytime highs around 17 °C on September 14. Light easterly to southeasterly winds limit advection of cooler highland air while high humidity and overcast skies reduce nocturnal radiative cooling. Official model consensus from agencies such as INMET and global ensembles shows minimal spread, with no strong cold surge or clear-sky warming expected. Historical September minima average near 12 °C, but the current moist, stable pattern favors values clustered in the mid-teens rather than extremes below 10 °C or above 20 °C. New 00 UTC and 12 UTC runs tomorrow will refine the exact minimum before market resolution.

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.
