Recent stabilization following early-week rains, combined with easterly to northeasterly flow and variable cloud cover, forms the main driver behind market-implied odds favoring a 20–21 °C high on August 30. Official Servicio Meteorológico Nacional guidance and most ensemble members indicate daytime maxima of 17–19 °C under partly cloudy skies, yet some global models show stronger subsidence and clearer intervals that could push readings to 20–22 °C. This narrow spread, typical for late-winter diurnal heating in the Río de la Plata region, explains the tight clustering around 20–21 °C outcomes. Traders weigh the latest model runs and boundary-layer moisture against historical August climatology, where highs rarely exceed 18 °C, while awaiting the final 48-hour forecast updates that will resolve the remaining uncertainty.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Minister Pistarini Intl Airport Station in degrees Celsius on 30 Aug '26.
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.Recent stabilization following early-week rains, combined with easterly to northeasterly flow and variable cloud cover, forms the main driver behind market-implied odds favoring a 20–21 °C high on August 30.
