Recent model runs show Buenos Aires under a post-frontal high-pressure regime with southerly flow and clear to partly cloudy skies overnight into September 13, favoring strong radiative cooling. Dew-point depressions and light winds support minimum temperatures near 4–7 °C at official stations, yet ensemble spread remains wide due to uncertain boundary-layer mixing and exact cloud cover. This uncertainty splits trader sentiment between the 9 °C-or-higher bucket (46.5 %) and the –1 °C-or-below bucket (46.0 %), with specific-centigrade contracts reflecting fine distinctions in how much cooling models project versus observed climatological September minima around 8–10 °C. Updated NWS and ECMWF guidance tonight will likely narrow resolution odds.

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 13 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 runs show Buenos Aires under a post-frontal high-pressure regime with southerly flow and clear to partly cloudy skies overnight into September 13, favoring strong radiative cooling.
