Recent ensemble model guidance from sources aligned with the Servicio Meteorológico Nacional indicates a mild winter pattern over Buenos Aires on August 19, 2026, with a daily maximum likely falling in the 14–17°C range amid variable cloud cover and light southerly flow. Persistent stratus and limited diurnal heating from reduced insolation, combined with a moderating cold front, have kept recent daily peaks near 15–16°C, aligning with the market’s evenly distributed probabilities across those outcomes. Minor differences in boundary-layer mixing and exact timing of any clearing could shift the peak by 1–2°C, while historical August maxima average near 18°C but current conditions reflect cooler-than-normal advection. Updated short-range runs expected later today will refine the precise threshold for resolution.

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.
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.Recent ensemble model guidance from sources aligned with the Servicio Meteorológico Nacional indicates a mild winter pattern over Buenos Aires on August 19, 2026, with a daily maximum likely falling in the 14–17°C range amid variable cloud cover and light southerly flow.
