**A cold air advection event driven by strong southerly winds is pushing minimum temperatures in Buenos Aires into the mid-single digits Celsius on September 12, 2026, creating tight clustering around 4–7°C in forecasts and near-even market odds.** Official and model guidance highlights a surge of cooler polar air under high pressure, with persistent cloud cover, relative humidity near 75–80%, and sustained winds of 25–30 km/h from the south that limit daytime recovery while enhancing nighttime cooling through advection and mixing. Forecasts from sources such as Noticias Ambientales, Yr.no, WeatherBug, and PredictWind converge on overnight lows between roughly 4°C and 8°C, with several runs pinpointing 4–5°C in the early morning hours of the 12th or into the 13th. Subtle differences in model handling of wind strength, cloud timing, and the exact arrival of the coldest air mass—plus minor urban heat-island buffering in the city—account for the split between the 6–7°C and 4–5°C brackets. Historical September minima in Buenos Aires average near 8–10°C, so this outbreak stands out as a sharp but not record-level drop, keeping higher-temperature outcomes at negligible implied probability. Traders are weighting the latest model consensus and official Servicio Meteorológico Nacional updates, which emphasize the wind-driven chill and limited radiative cooling under overcast skies as the dominant variables still in play before final overnight readings.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Minister Pistarini Intl Airport Station in degrees Celsius on 12 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=saez
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.**A cold air advection event driven by strong southerly winds is pushing minimum temperatures in Buenos Aires into the mid-single digits Celsius on September 12, 2026, creating tight clustering around 4–7°C in forecasts and near-even market odds.** Official and model guidance highlights a surge of cooler polar air under high pressure, with persistent cloud cover, relative humidity near 75–80%, and sustained winds of 25–30 km/h from the south that limit daytime recovery while enhancing nighttime cooling through advection and mixing.
