Recent forecasts from the Servicio Meteorológico Nacional and global models indicate a maximum of 22–24°C in Buenos Aires on September 19, driven by moderate northeasterly flow, increasing cloud cover, and the absence of strong subsidence or warm advection. Spring seasonal warming has lifted baseline highs above the long-term September average of roughly 18°C, yet a passing frontal boundary and limited insolation are capping further rises. Trader consensus, with 25°C at 42% and 24°C at 27.5% implied probability, aligns with this ensemble range while assigning lower odds to 26°C or higher outcomes that would require clearer skies or stronger northerly winds. Final resolution hinges on the official 24-hour maximum recorded at official stations.

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 19 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 the Servicio Meteorológico Nacional and global models indicate a maximum of 22–24°C in Buenos Aires on September 19, driven by moderate northeasterly flow, increasing cloud cover, and the absence of strong subsidence or warm advection.
