**Official observations from the Servicio Meteorológico Nacional and standard stations in Buenos Aires recorded a daily maximum of 19°C on September 11, 2026, driving the market's near-certain consensus on that outcome.** A sudestada brought southeast winds of 13–31 km/h with gusts to 50 km/h, advecting cooler, humid polar air and limiting daytime warming after milder conditions earlier in the month. Forecasts from the SMN and models projected highs of 17–18°C under mostly cloudy skies, yet actual measurements peaked at 19°C amid light precipitation and high humidity. This aligns with typical early-spring variability in the region, where cold-air intrusions can produce modest temperature swings. The market-implied odds reflect verified station data rather than pre-event models; revisions to official records or alternative station readings remain the primary, though low-probability, factors that could alter resolution.

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 11 Sep '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.
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.**Official observations from the Servicio Meteorológico Nacional and standard stations in Buenos Aires recorded a daily maximum of 19°C on September 11, 2026, driving the market's near-certain consensus on that outcome.** A sudestada brought southeast winds of 13–31 km/h with gusts to 50 km/h, advecting cooler, humid polar air and limiting daytime warming after milder conditions earlier in the month.
