Recent model consensus from the Servicio Meteorológico Nacional and ECMWF runs points to a daily minimum near 7°C in Buenos Aires on September 23, driven by northerly winds advecting milder, moister air after Tuesday’s polar front and radiative cooling under partly cloudy skies. This places the outcome in the 6–9°C range, though exact values hinge on wind speeds, cloud timing, and urban heat-island effects that can alter overnight lows by 1–2°C. Historical September minima average around 10°C, but the recent cold outbreak has kept probabilities split between sub-4°C scenarios if cooling intensifies and warmer 13°C+ outcomes if advection strengthens faster than expected; traders weigh the latest 00Z and 12Z model updates against these variables ahead of final resolution.

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 23 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.Recent model consensus from the Servicio Meteorológico Nacional and ECMWF runs points to a daily minimum near 7°C in Buenos Aires on September 23, driven by northerly winds advecting milder, moister air after Tuesday’s polar front and radiative cooling under partly cloudy skies.
