Recent forecasts from multiple models indicate a cool air mass advected by persistent southwesterly winds will limit daytime heating in Buenos Aires on September 22, with maximum temperatures most likely reaching 12–14°C under partly cloudy skies and possible light showers. This aligns with the market's leading implied probabilities for 14°C (38.5%) and 13°C (25.5%), reflecting trader assessment of limited insolation and post-frontal conditions following heavy rainfall on September 20. Historical September averages near 19°C provide context for the below-normal outcome, while model consensus on minimal warming and dew points in the single digits Celsius reinforces the tight clustering around these values ahead of final observations.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Minister Pistarini Intl Airport Station in degrees Celsius on 22 Sep '26.
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.Recent forecasts from multiple models indicate a cool air mass advected by persistent southwesterly winds will limit daytime heating in Buenos Aires on September 22, with maximum temperatures most likely reaching 12–14°C under partly cloudy skies and possible light showers.
