Trader consensus on Polymarket closely splits between 7°C (29%) and 8°C (25%) for Helsinki's highest temperature on April 3, driven by the latest Finnish Meteorological Institute (FMI) forecasts and ECMWF ensemble models projecting peak daytime highs in this range under southwesterly winds advecting milder Baltic Sea air. Current conditions feature partly cloudy skies and light winds around 3 m/s, enabling modest diurnal heating from morning lows near 0°C to mid-afternoon maxima, with 6°C as a nearby contender at 7.5% reflecting potential increased cloudiness. Differentiating factors include variable cloud cover impacting insolation at 60°N latitude—where spring solar angles limit extremes—and minor model disagreements on exact wind strengthening. FMI hourly updates through evening will clarify the peak, as observations supersede projections for resolution. Historical early-April averages hover near 7°C, underscoring the tight scientific uncertainty.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 3 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 7°C (29%) and 8°C (25%) for Helsinki's highest temperature on April 3, driven by the latest Finnish Meteorological Institute (FMI) forecasts and ECMWF ensemble models projecting peak daytime highs in this range under southwesterly winds advecting milder Baltic Sea air.
