Trader consensus around 22–24°C for São Paulo’s July 30 high reflects ensemble model runs from GFS and ECMWF showing modest daytime warming under subtropical high pressure, with light winds and limited cloud cover allowing some solar heating during the Southern Hemisphere winter. Official forecasts from sources such as the Met Office currently indicate a peak near 20–21°C, consistent with July climatology of 22–24°C averages at the Guarulhos reference station, though urban heat-island effects and exact timing of maximum temperature introduce 1–2°C run-to-run variability. The tight spread across outcomes stems from these small differences in insolation, boundary-layer mixing, and potential for brief cloud increases, with new model updates expected to refine the range before resolution.

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 30 Jul '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.
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.Trader consensus around 22–24°C for São Paulo’s July 30 high reflects ensemble model runs from GFS and ECMWF showing modest daytime warming under subtropical high pressure, with light winds and limited cloud cover allowing some solar heating during the Southern Hemisphere winter.
