The market's tight clustering around 16–18°C stems from consistent forecast guidance for persistent cloud cover and heavy rainfall over São Paulo on September 14, which will limit solar heating and cap daytime maxima well below the September climatological average of 23°C. Official model runs show southeasterly flow advecting moisture, with totals of 15–20 mm expected and near-100% cloud cover through the afternoon, keeping surface temperatures suppressed. Ensemble spreads produce the observed probability distribution, with 17°C favored where lighter midday rain allows modest warming and lower outcomes tied to heavier, prolonged precipitation. Resolution will hinge on official station readings, with any last-minute model shifts in rain timing the key variable still influencing trader positioning.

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.
