Current forecasts from multiple models indicate a mild spring day for Buenos Aires on September 10, with daytime highs near 17–19°C and overnight lows typically projected between 9–12°C under mostly clear to partly cloudy conditions and light easterly winds. Trader sentiment remains evenly split between sub-6°C and 16°C+ outcomes because early-September cold anomalies, including a 2.4°C minimum on the 6th linked to El Niño-enhanced variability, have heightened sensitivity to any late-model shifts in frontal passages or radiative cooling. Historical September lows average around 9°C, yet short-range ensemble spreads and rapid changes in steering patterns keep both tail risks live until final National Meteorological Service updates.

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.
