Recent model runs from meteorological agencies highlight variable cloud cover and a weak frontal boundary approaching São Paulo, creating uncertainty in peak daytime heating for May 18. This keeps implied probabilities tightly clustered around 19–21°C, as southerly airflow may suppress temperatures below the seasonal 22°C average while partial clearing could allow brief warming. Official guidance notes low precipitation risk but emphasizes how small shifts in humidity and wind patterns can alter maximum readings by 1–2°C. Traders weigh these near-term variables against historical May baselines, with resolution hinging on final verified observations from local stations.

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.
