**Official observations from Brazil's National Institute of Meteorology (INMET) and Sao Paulo-Guarulhos International Airport (SBGR) station confirm the highest temperature reached 28°C on May 9, 2026, under mostly cloudy conditions with light northerly winds ahead of an incoming cold front.** This aligns precisely with pre-event INMET forecasts projecting a 28°C maximum, driven by transient autumn ridge warming that temporarily boosted temperatures above May's climatological average of 22–23°C. Trader consensus at 100% implied probability for 28°C reflects this verified observational data from authoritative stations, representing skin-in-the-game agreement on the measured peak. Scenarios challenging this would require rare post hoc data revisions from SBGR or INMET, such as sensor recalibrations, though model-observation consistency makes shifts improbable as final reports finalize.

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 May '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Sao Paulo-Guarulhos International Airport Station once information is finalized, 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 to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.**Official observations from Brazil's National Institute of Meteorology (INMET) and Sao Paulo-Guarulhos International Airport (SBGR) station confirm the highest temperature reached 28°C on May 9, 2026, under mostly cloudy conditions with light northerly winds ahead of an incoming cold front.** This aligns precisely with pre-event INMET forecasts projecting a 28°C maximum, driven by transient autumn ridge warming that temporarily boosted temperatures above May's climatological average of 22–23°C.
