**Incoming cooler air from the southwest, driven by a post-frontal high-pressure system and strong winds, is the main factor shaping the market.** Latest forecasts from sources including the Met Office, Yr, and GFS-based models indicate overnight lows for September 21 in Buenos Aires ranging from 5–11 °C, with several runs pointing to 6–8 °C under partly cloudy skies and gusty conditions. This aligns with the 50 % implied probability on 7 °C or below, while the cluster around 8–11 °C (each near 20–21.5 %) reflects model spread and uncertainty in exact minimum timing. Recent heavy rain on September 20 cleared the way for this cooler, drier air mass, consistent with typical late-spring cold outbreaks in the region. Updated model runs and official observations through the night will likely determine final resolution.

This market will resolve to the temperature range that contains the lowest 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 lowest 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.**Incoming cooler air from the southwest, driven by a post-frontal high-pressure system and strong winds, is the main factor shaping the market.** Latest forecasts from sources including the Met Office, Yr, and GFS-based models indicate overnight lows for September 21 in Buenos Aires ranging from 5–11 °C, with several runs pointing to 6–8 °C under partly cloudy skies and gusty conditions.
