**Recent forecasts for São Paulo on September 10, 2026, center on a high of 21–23°C amid widespread cloud cover, intermittent rain, and a low-pressure system driving instability.** Official alerts from São Paulo’s Civil Defense highlight the risk of moderate to heavy rainfall (up to 70 mm possible) and gusty winds through Thursday, consistent with multiple meteorological sources showing suppressed daytime heating. Model runs, including those from Yr and other regional services, indicate peak temperatures near midday under mostly overcast skies, with rain reducing solar insolation and limiting the typical spring warming. September 2026 has already run several degrees cooler than the long-term average for the city, and the current pattern—marked by a frontal boundary and extratropical influences—reinforces this trend. The tight clustering of market-implied probabilities around 22°C (26%) and 23°C (23.5%), followed closely by 24°C and 21°C, reflects genuine forecast uncertainty: small differences in cloud timing, rainfall intensity, or wind direction could shift the daily maximum by 1–2°C. Traders are weighting the balance between modest diurnal recovery and persistent moisture that historically caps highs in similar setups. Updated model guidance and real-time observations through the day will likely refine these odds ahead of resolution.

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.
