Current forecast models from agencies like INMET and international sources point to overnight minimum temperatures in São Paulo around 19–21°C on August 30, 2026, amid a persistent warm, dry air mass over the plateau city. This setup keeps trader-implied probabilities tightly clustered between 17°C-or-below and 20°C outcomes, reflecting model uncertainty in nocturnal radiative cooling under partly cloudy skies, light variable winds, and urban heat-island effects that can elevate readings by 1–2°C relative to rural stations. Recent days of above-average warmth, driven by a strong South Atlantic subtropical high with minimal polar-front influence, have limited cold-air advection and kept humidity moderate, suppressing the sharper drops typical of clearer, calmer winter nights. Historical August climatology shows average minima near 13–15°C, but this season’s positive anomaly narrows the window for sub-18°C readings unless enhanced clear-sky conditions materialize before dawn. Updated model runs and official station observations expected later today remain the key near-term catalysts.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
