Current forecast models indicate a minimum temperature near 10°C for Buenos Aires on August 31, consistent with late-winter climatology where overnight radiative cooling under high pressure and light easterly winds typically produces lows of 9–12°C. Trader sentiment remains closely balanced between the 7°C-or-below and 17°C-or-higher outcomes because small shifts in cloud cover, dew-point depression, or wind speed can alter the exact low by several degrees, while ensemble guidance shows modest spread around the mean. Historical analogs for late August confirm that clear, calm nights favor the colder tail, whereas any increase in moisture or mixing pushes values higher. Final model runs and observational updates over the next 48 hours will likely narrow these probabilities ahead of resolution.

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 31 Aug '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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.Current forecast models indicate a minimum temperature near 10°C for Buenos Aires on August 31, consistent with late-winter climatology where overnight radiative cooling under high pressure and light easterly winds typically produces lows of 9–12°C.
