**Forecasts from multiple models indicate a maximum temperature near 11–12°C for Buenos Aires on September 13, with light southerly winds, clearing skies after overnight cooling, and high pressure limiting diurnal warming.** This places the market’s near-even split between 12°C (40.0%) and 13°C (39.5%) in line with ensemble spreads, where small differences in boundary-layer mixing or timing of cloud dissipation can shift the daily peak by 1°C. Historical September averages hover around 15–17°C, so the current cool anomaly stems from a recent cold-air outbreak and persistent onshore flow. Traders appear to weigh the latest high-resolution runs showing a 10–12°C range against the possibility of slightly stronger insolation if winds weaken faster than expected. Updated National Meteorological Service guidance and afternoon model cycles will likely refine the exact maximum 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 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.**Forecasts from multiple models indicate a maximum temperature near 11–12°C for Buenos Aires on September 13, with light southerly winds, clearing skies after overnight cooling, and high pressure limiting diurnal warming.** This places the market’s near-even split between 12°C (40.0%) and 13°C (39.5%) in line with ensemble spreads, where small differences in boundary-layer mixing or timing of cloud dissipation can shift the daily peak by 1°C.
