Recent forecasts from the National Meteorological Service and global models indicate a minimum near 7–8°C for Buenos Aires on September 23, driven by a post-frontal shift to northerly winds advecting milder, moister air after Tuesday’s polar outbreak. Overnight radiative cooling under partly cloudy skies and light winds will set the low, with model consensus showing limited overnight drop once the warmer flow strengthens. Trader emphasis on the 3°C-or-below outcome at 45% likely reflects lingering uncertainty from the recent cold snap and possible model spread on exact timing of the wind change, while the 36.5% on 13°C or higher captures upside risk if advection is stronger than expected. Historical September minima average around 8–10°C, underscoring the transitional spring pattern.

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 forecasts from the National Meteorological Service and global models indicate a minimum near 7–8°C for Buenos Aires on September 23, driven by a post-frontal shift to northerly winds advecting milder, moister air after Tuesday’s polar outbreak.
