This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 1 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 heavily favors 20°C (35.5%) and 21°C (34.5%) as Helsinki's highest temperature on May 1, driven by the latest ECMWF and GFS model ensembles projecting peaks around 20-21°C under a persistent high-pressure ridge over Scandinavia, fostering clear skies, light southerly winds, and maximal insolation. The Finnish Meteorological Institute's (FMI) guidance for Helsinki-Kaisaniemi station shows a more conservative 16-17°C at 15:00 local time, but traders weigh warmer signals from yr.no airport forecasts (21°C) and recent April warming trends, with highs reaching 16°C mid-month. Differentiating factors include model spread on boundary-layer mixing and transient cloud breaks, against a May 1 climatological average of 12-14°C. Overnight 00Z updates and morning soundings could refine odds before resolution.
