Current forecasts from ECMWF and regional models indicate a minimum temperature near 8°C for Buenos Aires on September 23, with overnight radiative cooling under partly cloudy skies and light northerly winds limiting further drops. This places the most likely outcome in the 7–9°C range, yet market-implied odds remain split between 3°C or below (45%) and 13°C or higher (40.5%) because small shifts in cloud cover, wind direction, or model bias can alter the overnight low by several degrees. Late-September climatology shows typical minima of 8–12°C, but recent model runs have trended slightly warmer than earlier guidance, underscoring the sensitivity of short-range temperature forecasts to evolving synoptic patterns.

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.
