Recent official forecasts from Argentina’s Servicio Meteorológico Nacional (SMN) project a maximum of 19°C for Buenos Aires on September 9 amid a post-cold spell warming trend driven by northerly advection and partly cloudy skies. Ensemble guidance and global models cluster between 17–19°C, with limited diurnal heating expected under moderate cloud cover and light winds that reduce boundary-layer mixing. The tight market split between 19°C (30.5%) and 20°C (33.0%) reflects uncertainty in how much additional warming may occur if skies clear more than anticipated or if model bias toward cooler solutions persists. Updated SMN briefings and next model cycles will likely refine the outcome before resolution.

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 9 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 official forecasts from Argentina’s Servicio Meteorológico Nacional (SMN) project a maximum of 19°C for Buenos Aires on September 9 amid a post-cold spell warming trend driven by northerly advection and partly cloudy skies.
