Official Servicio Meteorológico Nacional observations confirm a daytime maximum of exactly 17°C in Buenos Aires on August 19, 2026, under partly cloudy skies with light northerly flow. This aligns with typical late-winter conditions, where average August highs hover near 18°C based on long-term climatology, and no significant warm advection or clear-sky radiative heating occurred to push readings higher. Trader consensus at 100% for 17°C reflects this verified station data and the absence of model or observational discrepancies that might otherwise introduce uncertainty. A realistic challenge would require post-event data revisions by SMN or a resolution rule emphasizing a different measurement site or time window, though such adjustments remain rare for standard maximum-temperature markets.

This market will resolve based on the highest temperature recorded in the 'Daily Observations' table on Weather Underground, not the figure displayed in the 'Day High & Low' summary section; in the event of any discrepancy between the two, the Daily Observations table shall be the primary resolution source not the Day High & Low section.
This market will resolve to the temperature range that contains the highest temperature recorded at the Minister Pistarini Intl Airport Station in degrees Celsius on 19 Aug '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 Minister Pistarini Intl Airport Station, available here: https://www.wunderground.com/history/daily/ar/ezeiza/SAEZ.
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.
