Recent cold front passage and associated precipitation across the Buenos Aires region on September 20 have introduced cooler air and variable cloud cover, creating forecast spread for the September 23 daily maximum. Northerly flow is expected to advect milder air northward, yet model consensus from sources like the SMN and international guidance shows afternoon highs most likely between 17–19°C, with potential for 20–22°C under clearer skies or stronger warming. Lingering moisture and wind shifts could suppress peak heating, while historical September baselines near 18°C underscore the narrow range. Traders weigh these atmospheric dynamics against the imminent resolution window, with official observations determining the exact maximum.

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 23 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 cold front passage and associated precipitation across the Buenos Aires region on September 20 have introduced cooler air and variable cloud cover, creating forecast spread for the September 23 daily maximum.
