A passing cold front from the southwest is the main driver keeping the daytime high in Buenos Aires near 12–14 °C on August 18, with official Servicio Meteorológico Nacional guidance and supporting model runs pointing to a peak around 13–14 °C under overcast skies and light southerly flow. In Southern Hemisphere winter, this advection of cooler maritime air suppresses typical August maxima (historically near 15–17 °C) while limited boundary-layer mixing and persistent cloud cover reduce warming potential. Modest spread across forecast timing and wind strength keeps the market-implied odds concentrated on 14 °C (59.5 %) and 13 °C (29 %), reflecting trader consensus on these thresholds as the most likely resolution outcomes ahead of final observations.

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 18 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.
