**Forecast models and recent observations position 20–22°C as the leading outcomes for Buenos Aires’s August 30 high temperature, with 21°C holding the highest market-implied probability at 38.5%.** August climatology shows average daily maxima near 17–18°C, but persistent high pressure, light easterly flow, and mostly clear to partly cloudy skies have supported daytime warming above seasonal norms in recent days. Multiple numerical weather prediction runs, including GFS and ECMWF guidance referenced across services, converge on afternoon readings in the upper teens to low 20s Celsius under stable conditions with minimal precipitation risk. Official Servicio Meteorológico Nacional (SMN) briefings emphasize continued dry, mild weather through early September, though model spread and potential for increased cloud cover introduce realistic uncertainty around exact peak values. New observational data and updated model runs expected later on August 29 will likely refine these probabilities ahead of market resolution.

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.
