Recent model runs from ECMWF and GFS indicate Buenos Aires overnight lows near 5–10°C on August 25 amid variable northeasterly flow, stable high pressure, and modest radiative cooling under partly cloudy skies with dew points around 2–6°C. Ongoing cool anomalies from recent days—when minima reached 4–7°C under lingering polar air advection—have kept the market tightly clustered, with roughly equal implied probabilities for sub-3°C extremes versus milder outcomes above 11°C. Key differentiating factors include exact wind shifts that could enhance or suppress nocturnal cooling, cloud cover timing that moderates temperature drops, and local urban effects near the official Servicio Meteorológico Nacional station. Traders are monitoring the next model updates and surface observations for any rapid changes ahead of resolution.

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
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
