Trader consensus on Polymarket assigns just 3.5% implied probability each to 8°C or below, 9°C, and 10°C highs in Helsinki on May 9, reflecting low confidence in prolonged cool conditions amid latest Finnish Meteorological Institute (FMI) forecasts showing daytime peaks near 11–13°C under northerly winds and partial clearing. Recent 24-hour model updates from ECMWF and GFS ensembles indicate a strengthening high-pressure ridge over Scandinavia, boosting diurnal heating and limiting cold air advection, which historically yields May 9 averages around 13°C at Helsinki-Vantaa station. Closely matched leading outcomes in the 11–14°C range stem from uncertainty in cloud cover persistence and boundary layer mixing, with overcast scenarios capping at lower teens versus sunnier runs pushing toward 14°C; new FMI briefings and 12Z model runs expected tomorrow could refine this spread before resolution via official FMI observations.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 9 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 assigns just 3.5% implied probability each to 8°C or below, 9°C, and 10°C highs in Helsinki on May 9, reflecting low confidence in prolonged cool conditions amid latest Finnish Meteorological Institute (FMI) forecasts showing daytime peaks near 11–13°C under northerly winds and partial clearing.
