**Cool early-spring conditions in Buenos Aires are positioning 12–13°C as the most likely daily maximum on September 13, 2026, according to current forecast consensus.** Multiple models and official guidance show a high-pressure system building behind a recent cold front, with light southerly to easterly winds, clearing skies, and minimal cloud cover limiting daytime heating. Overnight lows near 4–6°C will give way to gradual warming, but the stable atmospheric setup and seasonal norms for mid-September keep the peak modest. Forecasts from sources including WeatherBug (~12°C), Wunderground (~11°C), Met Office (10°C), Yr.no (~9–10°C), and PredictWind (10–12°C) converge on this range, with little model spread noted. Recent observations on September 12—cloudy skies, light drizzle, and highs around 9–12°C—reflect the lingering influence of cooler maritime air that is only slowly moderating. Traders have priced the highest probabilities on 12°C (33%) and 13°C (43.5%), reflecting this tight scientific consensus while assigning lower odds to warmer outliers that would require stronger northerly flow or greater insolation than currently expected. Updated model runs or official briefings from regional meteorological services remain the key near-term catalysts.

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 13 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.**Cool early-spring conditions in Buenos Aires are positioning 12–13°C as the most likely daily maximum on September 13, 2026, according to current forecast consensus.** Multiple models and official guidance show a high-pressure system building behind a recent cold front, with light southerly to easterly winds, clearing skies, and minimal cloud cover limiting daytime heating.
