Recent forecasts from multiple meteorological sources indicate a daytime high in São Paulo on September 15, 2026, most likely between 18–21°C amid persistent cloud cover, light rain or drizzle, and southerly winds limiting daytime heating. September 2026 has run notably cooler than the long-term average high near 23°C, with September 14 temperatures held to 12–17°C under overcast, rainy conditions. Model consensus points to modest warming on the 15th but suppressed maxima due to high humidity, reduced insolation, and stable atmospheric conditions rather than strong frontal passages. Trader-implied probabilities cluster on 19–20°C outcomes because these align with the narrow range of current numerical guidance and historical analogs for similar synoptic setups; 21°C or higher would require clearer skies or a stronger ridge, while sub-18°C would need unexpectedly persistent rain and stronger cold advection. Updated model runs and observational data from the next 12–24 hours will likely refine these probabilities 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.
