Recent forecasts from sources including BBC Weather and timeanddate.com point to a high near 18°C (65°F) for Buenos Aires on August 26 under northeasterly flow and high pressure near 1024 hPa, with modest daytime heating from partial insolation and stable conditions following cooler readings around 13–14°C on August 25. Late-winter climatology supports typical maxima of 15–18°C, but model consensus shows minor spreads tied to exact cloud cover, humidity trends, and peak timing that could nudge readings to 19–20°C. Traders have clustered probability on these warmer bins, reflecting skin-in-the-game assessment of subtle synoptic warming amid low precipitation risk and light winds, while colder outcomes remain less likely absent cold-air advection.

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 26 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 is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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 forecasts from sources including BBC Weather and timeanddate.com point to a high near 18°C (65°F) for Buenos Aires on August 26 under northeasterly flow and high pressure near 1024 hPa, with modest daytime heating from partial insolation and stable conditions following cooler readings around 13–14°C on August 25.
