**A cold front advancing across central Argentina is the dominant driver behind current market odds favoring a 17°C or 18°C high in Buenos Aires on September 21.** Southwesterly winds of 25–40 km/h are expected to advect cooler, drier air behind the front, suppressing daytime warming despite peak spring solar insolation near the equinox. Official model consensus from GFS and regional guidance points to partly cloudy skies with limited cloud cover after morning clearing, yielding an afternoon maximum in the 15–17°C range—slightly below seasonal norms for late September. Recent observations show the preceding days featured warmer, more humid conditions with light rain, setting up the sharp temperature drop. Traders appear to weigh the strong post-frontal signal against minor model spread in exact peak timing and wind mixing, which could allow brief excursions to 18°C under clearer breaks. No major data releases are pending 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 21 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.**A cold front advancing across central Argentina is the dominant driver behind current market odds favoring a 17°C or 18°C high in Buenos Aires on September 21.** Southwesterly winds of 25–40 km/h are expected to advect cooler, drier air behind the front, suppressing daytime warming despite peak spring solar insolation near the equinox.
