This market will resolve to the temperature range that contains the highest temperature recorded at the Minister Pistarini Intl Airport Station in degrees Celsius on 18 Apr '26. The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Minister Pistarini Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ar/ezeiza/SAEZ. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.

Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Trader consensus on Polymarket prices a tight race among 26–28°C outcomes for Buenos Aires' highest temperature on April 18, reflecting short-range forecast uncertainty from models like GFS and ECMWF, which show ensemble means near 27°C but diverge by 2–3°C due to variable cloud cover, sea breeze timing, and southerly wind moderation. Recent developments include above-normal April temperatures (+1°C monthly anomaly per SMN monitoring), with highs of 26°C on April 12 and a 26°C forecast for today (April 16) amid a subtropical ridge fostering warm advection. Cooling signals from incoming fronts temper optimism for 29°C+, while urban heat island effects boost upper-20s potential. Watch SMN updates and overnight model runs for resolution shifts before the diurnal peak at official stations like Aeroparque.
