This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa 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 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 closely splits between a highest temperature of 13°C (57% implied probability) and 14°C or higher (53.5%), reflecting inherent uncertainty in short-range weather forecasts amid variable spring conditions in Helsinki. The latest Finnish Meteorological Institute (FMI) guidance points to a cooldown on April 18 after Friday's projected 16°C high, with daytime maxima around 9–12°C under northeast winds (3–5 m/s) and low precipitation risk (<10%), but ensemble spreads from models like ECMWF allow warmer outcomes if cloud cover clears for greater solar insolation. Historical late-April averages hover near 10°C, with northerly flow versus potential high-pressure ridging as key differentiators; expect refined odds from daily 00Z/12Z model updates before resolution.
