**Forecast model consensus for Buenos Aires on September 17 centers on a high near 20–23°C under northerly flow and mostly clear skies, producing the tight clustering of market-implied odds around 24–26°C.** Northerly winds are advecting warmer, moister air from subtropical latitudes while high pressure supports strong daytime insolation and a pronounced diurnal range typical of early spring at 34°S. Official Servicio Meteorológico Nacional guidance and ensemble guidance show limited spread, but small differences in boundary-layer mixing, exact wind speed, or cloud timing can shift the peak by 1–2°C. Traders appear to assign modest additional probability to the upper end of guidance given the recent warming trend and potential for slightly stronger northerly advection than earlier runs suggested. New model cycles and the official daily forecast update remain the key near-term catalysts.

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.
