Recent forecasts from Brazilian meteorological services indicate a cold front advancing across São Paulo state, introducing cooler maritime air and increased cloud cover that limits daytime solar heating on June 16. This setup favors maximum temperatures near 18–20°C, aligning with the market’s tight clustering around those outcomes, as models show modest variability in frontal timing and precipitation intensity that could shift the daily peak by 1–2°C. Historical June climatology places typical highs near 22°C, but the current synoptic pattern—marked by post-frontal stabilization and possible light rain—explains the downward pressure on extremes above 21°C. Updated INMET guidance and regional model runs over the next 24 hours will likely refine these probabilities as the front’s exact position becomes clearer.

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 16 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.Recent forecasts from Brazilian meteorological services indicate a cold front advancing across São Paulo state, introducing cooler maritime air and increased cloud cover that limits daytime solar heating on June 16.
