Recent weather model consensus from agencies including the Servicio Meteorológico Nacional and international sources indicates a minimum temperature near 10–11°C for Buenos Aires on August 31, driven by easterly flow and stable high pressure limiting nocturnal cooling. This places the outcome near the midpoint of the distribution, where small forecast revisions in boundary-layer moisture or wind speed can shift the low by 2–3°C. Milder-than-average winter conditions so far have reduced the likelihood of strong polar outbreaks, yet residual model spread maintains roughly equal implied probabilities for the 17°C-or-higher and 7°C-or-below ranges. Updated runs from the next 24–48 hours will clarify whether any weak frontal passage alters the overnight minimum.

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.Recent weather model consensus from agencies including the Servicio Meteorológico Nacional and international sources indicates a minimum temperature near 10–11°C for Buenos Aires on August 31, driven by easterly flow and stable high pressure limiting nocturnal cooling.
