**Official meteorological records confirm a daily maximum of 19.5°C at Buenos Aires stations on August 20, 2026, producing the market’s 100% consensus on the 19°C outcome.** A southerly flow and persistent cloud cover limited stronger warming, yet daytime temperatures still peaked near 20°C amid a broader cold air mass that kept the monthly average below normal. Pre-event forecasts from the National Meteorological Service had centered on 14–18°C maxima with high humidity and no precipitation, but observed data exceeded those projections by several degrees. With resolution now complete, only discrepancies in station selection or rounding rules could theoretically alter the result, though such adjustments remain improbable given consistent observational agreement.

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 20 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.
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.**Official meteorological records confirm a daily maximum of 19.5°C at Buenos Aires stations on August 20, 2026, producing the market’s 100% consensus on the 19°C outcome.** A southerly flow and persistent cloud cover limited stronger warming, yet daytime temperatures still peaked near 20°C amid a broader cold air mass that kept the monthly average below normal.
