Recent forecasts from sources including the Servicio Meteorológico Nacional and global models indicate mild conditions for Buenos Aires on September 11, with daytime highs near 16–19°C and overnight lows expected around 10–12°C under increasing southeasterly flow. Trader sentiment remains split near 50% between sub-8°C and 17°C+ outcomes because of model spread on the arrival and intensity of a polar air mass, which could enhance nocturnal radiative cooling if skies clear or deliver stronger advection if winds strengthen earlier. Cloud cover, dew points near 9–11°C, and steering patterns from high pressure to the east introduce key variables that differentiate cooler versus milder resolution scenarios, with updated model runs and local observations likely to narrow the range before the date.

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 11 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 sources including the Servicio Meteorológico Nacional and global models indicate mild conditions for Buenos Aires on September 11, with daytime highs near 16–19°C and overnight lows expected around 10–12°C under increasing southeasterly flow.
