Forecast models from sources like Climatempo and regional monitoring point to a warm, dry air mass dominating São Paulo on August 29, 2026, driving daytime highs primarily into the 33–34°C range through strong solar insolation under partly cloudy skies and northwest winds of 15–25 km/h. Low relative humidity (dropping to 30–40% in the afternoon) limits evaporative cooling while enhancing surface heating, consistent with late-winter patterns where typical August maxima average near 22°C. Official updates from IPMet and international agencies show stable conditions with minimal precipitation risk, supporting the market's emphasis on 33°C (52%) and 34°C (25%) as leading outcomes over cooler or more extreme thresholds. New afternoon observations and model runs will refine the exact peak before resolution.

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 29 Aug '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.
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.Forecast models from sources like Climatempo and regional monitoring point to a warm, dry air mass dominating São Paulo on August 29, 2026, driving daytime highs primarily into the 33–34°C range through strong solar insolation under partly cloudy skies and northwest winds of 15–25 km/h.
