Current forecasts from multiple models place the overnight minimum in Buenos Aires on September 18 around 13–15 °C under partly cloudy skies with light northeast winds, slightly above the long-term September average low near 10–11 °C. This mild pattern stems from persistent high pressure and onshore flow that limits radiative cooling, with no strong cold fronts expected in the 48-hour window. Model consensus supports temperatures well above 8 °C while remaining below 18 °C, yet small differences in cloud cover, wind speed, or boundary-layer mixing can shift the exact low by 1–2 °C. Trader sentiment therefore splits evenly between the lower and higher brackets, reflecting genuine uncertainty in short-range guidance rather than any dramatic shift in atmospheric conditions. Updated model runs and observational data over the next day will likely tighten these probabilities.

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.
