**Forecast models and official guidance ahead of August 21 pointed to a minimum near 4°C in Buenos Aires.** Clear skies overnight combined with light southerly winds promoted strong radiational cooling, consistent with typical late-winter patterns under high-pressure influence. Ensemble guidance showed tight clustering around 4–6°C, with 40 °F (≈4.4 °C) appearing in multiple operational runs, supporting the market’s heavy 92.5 % weighting on exactly 4 °C. Traders viewed this as the most probable resolution given historical analogs and the absence of significant warm-air advection. A modest upward revision could occur only if unobserved cloud cover or localized urban heat effects raised the actual low above the modeled value; conversely, any earlier clearing or calmer conditions would have reinforced the lower end of the range.

This market will resolve based on the lowest 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 lowest temperature recorded at the Minister Pistarini Intl Airport Station in degrees Celsius on 21 Aug '26.
The resolution source for this market will be information from Wunderground, specifically the lowest 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.**Forecast models and official guidance ahead of August 21 pointed to a minimum near 4°C in Buenos Aires.** Clear skies overnight combined with light southerly winds promoted strong radiational cooling, consistent with typical late-winter patterns under high-pressure influence.
