Current forecasts from multiple meteorological models, including GFS and ECMWF runs, position 13°C as the most likely daily maximum for Buenos Aires on September 7, driven by a stable high-pressure ridge and northerly flow bringing mild air under partly cloudy skies. This aligns with observed trends on September 6, when highs reached only 9–10°C amid southerly winds and clear conditions. September climatology typically sees averages near 18°C, making the cooler pattern notable yet consistent across short-range guidance with minimal model spread. Light winds and low humidity should limit diurnal warming, while any overnight model adjustments could shift probabilities before official Servicio Meteorológico Nacional observations finalize the outcome.

The resolution source for this market will be information from NOAA, specifically the highest 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.
