**Trader consensus strongly favors a daily high of 21°C or below (99.8% implied probability) for São Paulo on September 20, 2026, reflecting real-time meteorological data and the day’s observed conditions.** Persistent cloud cover, light rain or drizzle, and a cooler-than-average air mass have suppressed daytime warming throughout the period. Multiple official and model sources, including forecasts from ClimaTempo, the Met Office, and WeatherBug, project a maximum around 20–23°C (roughly 68–73°F), with many hourly readings and station reports showing peaks near or below 21°C amid high humidity and northerly winds. This aligns with September 2026 already ranking as the rainiest on record in the city since 1943, driven by an unusually active rain pattern that has lowered temperatures several degrees below the long-term September average high of ~23–25°C. The market’s near-certainty reflects skin-in-the-game assessment of converging forecast guidance and in-day observations from INMET-linked stations. A realistic challenge would require unexpected rapid clearing and stronger solar heating late in the day to push an official reading above 21°C, though current model consensus and observed trends make this highly improbable.

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.
