**A cold front passage and subsequent southwest winds are the main drivers positioning the lowest temperature in Buenos Aires on September 3 near or below 9–12 °C.** Official forecasts from sources such as WeatherBug, Yr.no, and Worldmeteo show overnight lows of 8–12 °C under clearing skies after earlier showers, with dry air and moderate westerly flow enhancing radiative cooling. This aligns with September climatology, where the average minimum is approximately 9 °C. Trader consensus reflected in the 45.5% implied probability for 9 °C or below, versus lower odds for warmer bins, tracks the model consensus for post-frontal stabilization and minimal cloud cover overnight. Updated model runs through the evening of September 2 reinforced this cooler trajectory ahead of resolution.

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.
