Recent official forecasts from Argentina’s National Meteorological Service and global models indicate a high of 17–19°C in Buenos Aires on September 9 under mostly cloudy to partly cloudy skies with light northeasterly winds. This warming follows a cooler weekend as northerly flow advects milder air, with minimal precipitation risk allowing modest daytime heating. Trader consensus clusters tightly on 19°C and 20°C because small differences in cloud timing, exact wind direction, or boundary-layer mixing can shift the peak by 1°C; models show limited spread but acknowledge typical uncertainty in urban heat-island effects and insolation under variable cover. Upcoming high-resolution runs and afternoon observations will refine the final maximum.

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.
