**Forecasts from multiple models indicate a high near 18°C for Buenos Aires on August 31, driven by stable high pressure, light easterly winds off the Atlantic, and variable cloud cover that limits daytime warming.** This late-winter setup aligns with climatological norms of 16–18°C maxima, with recent observations showing mild conditions and no significant frontal systems or warm advection to push temperatures higher. Trader sentiment, reflected in the elevated implied probabilities for 19–20°C (over 75% combined), likely incorporates model spread and the potential for clearer skies or slight warming trends in updated runs, while downweighting cooler outcomes below 18°C. Resolution hinges on the official daily maximum from Servicio Meteorológico Nacional data, with low precipitation risk supporting steady but not exceptional heating.

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.
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.
