**Forecast uncertainty around a passing cold front and variable overnight cooling drives the closely matched market odds for Buenos Aires' minimum temperature on September 21, 2026.** Current model consensus points to a daytime high near 17°C under partly cloudy skies with strong southwest winds, followed by a nighttime low in the 7–11°C range. Multiple sources (including WeatherBug, Met Office, and Yr.no) show the minimum hovering near the 7°C threshold, reflecting a shift to cooler maritime air after earlier warmth and possible thunderstorms on the 20th. Key differentiating factors include the exact timing and strength of the frontal passage, wind speeds (higher gusts enhance mixing and limit radiative cooling), and cloud cover, which can trap heat versus clear skies that allow stronger temperature drops. Historical September baselines in Buenos Aires feature average lows around 10–12°C, so deviations depend on these short-term atmospheric details. With resolution imminent and model runs still diverging on the precise overnight minimum, trader sentiment remains split between the sub-7°C and above-17°C extremes, while mid-range outcomes (9–16°C) reflect the spread of plausible scenarios. Updated official guidance from agencies like Argentina’s SMN will likely clarify the outcome in the coming hours.

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 21 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.**Forecast uncertainty around a passing cold front and variable overnight cooling drives the closely matched market odds for Buenos Aires' minimum temperature on September 21, 2026.**
