Recent cold air advection and clear skies produced a sharp drop to 2.4 °C on September 6 in Buenos Aires, the lowest minimum so far this month and well below the 9 °C September average. Official forecasts from multiple models now indicate moderating conditions for September 9, with overnight lows expected near 10–12 °C under increasing cloud cover and light northeasterly flow. This contrast between the recent observed minimum and the milder ensemble guidance explains why traders assign the highest implied probability (60 %) to 5 °C or below while still pricing notable chances for 9–10 °C outcomes. Updated National Meteorological Service runs and any late-model shifts in steering patterns will be the key near-term catalysts.

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 9 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 cold air advection and clear skies produced a sharp drop to 2.4 °C on September 6 in Buenos Aires, the lowest minimum so far this month and well below the 9 °C September average.
