This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 2 May '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 Helsinki Vantaa Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/fi/vantaa/EFHK. To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C. This market can not resolve to "Yes" until all data for this date has been finalized. 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. 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 30.5% implied probability for a 19°C high in Helsinki on May 2, edging out 20°C at 23.5%, amid close competition reflecting short-range forecast uncertainty just two days out. The Finnish Meteorological Institute's latest guidance projects around 13°C under low-precipitation (<10%) conditions with southwest winds at 3-6 m/s, but traders anticipate upside from a recent mild trend—14°C observed April 30, 16°C forecast May 1—and potential high-pressure ridging boosting solar insolation if clouds thin further. Differentiating 19°C versus 20°C hinges on boundary-layer mixing, southerly advection warmth, and urban heat at the Helsinki-Vantaa station; watch 12Z ECMWF/GFS updates for refinements before resolution. Historical early-May highs average 12°C but vary widely, underscoring model conservatism.
