Current forecasts from meteorological agencies point to an overnight low near 4°C in Buenos Aires on August 21, driven by typical mid-winter radiative cooling under clear or partly cloudy skies combined with light southerly winds. Subtle differences in model outputs—such as the strength of any incoming high-pressure ridge versus residual moisture from prior fronts—create tight clustering of market probabilities across 1–5°C outcomes. Historical August minima average 8–9°C but occasionally reach 4°C or below during cold-air outbreaks; traders weigh updated runs from regional models against the risk of slightly stronger cooling if winds calm further overnight. Official Servicio Meteorológico Nacional station readings will determine resolution, with measurement precision and urban heat-island effects adding minor uncertainty to the final minimum.

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.
