Current forecast models from agencies like Brazil's CPTEC and global ensembles point to a cool June day in São Paulo driven by a passing cold front and increased cloud cover, keeping daytime highs likely between 14–16°C. Recent observations show temperatures several degrees below seasonal normals around 22°C, with light winds and possible showers limiting solar heating and favoring the market's leading 15°C outcome at 30.5% implied probability. Model spread on exact maximums—sensitive to timing of frontal passage and boundary-layer mixing—explains the tight clustering around 14°C and 16°C, while historical June variability underscores why traders assign lower weight to extremes. Updated runs ahead of resolution will refine these projections.

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 24 Jun '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.Current forecast models from agencies like Brazil's CPTEC and global ensembles point to a cool June day in São Paulo driven by a passing cold front and increased cloud cover, keeping daytime highs likely between 14–16°C.
