**Diverging short-range model guidance on overnight radiative cooling and shifting wind patterns is the main factor splitting trader sentiment nearly evenly between an 11°C-or-lower minimum (42.5%) and a 21°C-or-higher minimum (41.0%) for Buenos Aires on September 25.** Current northerly flow and partly cloudy skies favor milder overnight lows near 13–15°C according to the latest ECMWF and GFS runs, yet any earlier southerly shift or clearer skies could enhance cooling below 12°C, while persistent cloud or stronger mixing could keep the minimum above 20°C. This genuine forecast spread, typical for spring transitional days when synoptic features evolve rapidly, explains the clustered probabilities around 13–17°C outcomes and the market’s reflection of real uncertainty in official Servicio Meteorológico Nacional guidance and ensemble spreads. Updated model cycles and local observations over the next 24 hours will likely resolve the range.

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.
