Recent northerly wind shifts are advecting warmer, humid air into Buenos Aires ahead of a stable high-pressure ridge, driving model consensus toward afternoon highs of 23–25 °C on September 24 under mostly sunny skies that enhance daytime heating. Official Servicio Meteorológico Nacional guidance and ensemble forecasts highlight this advection and reduced cloud cover as the dominant factors lifting probabilities for 25 °C (46 % implied) over cooler outcomes. Minor model spread around peak insolation and boundary-layer mixing keeps 24 °C and 26 °C viable, while historical September maxima near 20 °C underscore the current anomaly. Updated runs before landfall of the warm sector will refine these trader-implied odds.

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 24 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 northerly wind shifts are advecting warmer, humid air into Buenos Aires ahead of a stable high-pressure ridge, driving model consensus toward afternoon highs of 23–25 °C on September 24 under mostly sunny skies that enhance daytime heating.
