**Persistent cloud cover and heavy rainfall during an exceptionally wet September suppressed daytime heating in São Paulo on September 20, 2026, keeping the official maximum temperature at or below 21°C.** September 2026 ranks as the wettest on record for the city since 1943, with rainfall through mid-month already exceeding three times the climatological average; this pattern of widespread cloudiness and precipitation continued into the third week, limiting solar insolation and preventing typical afternoon warming. Official station data, including hourly observations peaking near 21°C amid overcast skies and light rain or drizzle, align with the market’s near-certain outcome for 21°C or below. Historical September maxima average around 23–25°C under clearer conditions, but the anomalous moisture and reduced sunshine this month produced cooler anomalies. The only realistic way this consensus could shift is if a revised post-event analysis from the primary monitoring station (e.g., Mirante de Santana or Congonhas) reported a marginally higher reading due to micro-climate or measurement adjustments—though current verified observations make such a revision highly improbable.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 20 Sep '26.
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.**Persistent cloud cover and heavy rainfall during an exceptionally wet September suppressed daytime heating in São Paulo on September 20, 2026, keeping the official maximum temperature at or below 21°C.**
