Trader sentiment for São Paulo’s August 9 maximum centers on numerical weather models projecting a high near the 24–25 °C seasonal average, driven by a cooler post-frontal air mass advecting southeastward across Brazil. Limited diurnal heating from partial cloud cover, modest boundary-layer mixing, and typical wintertime subsidence under high pressure keep temperatures tightly clustered around climatological norms. Small forecast spreads between 24 °C and 26 °C hinge on exact frontal timing, low-level moisture, and insolation differences; official guidance from INMET and global ensembles shows low risk of significant deviation, aligning market-implied odds with historical August variability of roughly ±2 °C.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Sao Paulo-Guarulhos International Airport Station in degrees Celsius on 9 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Sao Paulo-Guarulhos International Airport Station, available here: https://www.wunderground.com/history/daily/br/guarulhos/SBGR.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
