Recent short-term forecasts from the Finnish Meteorological Institute and European Centre for Medium-Range Weather Forecasts show Helsinki’s May 18 daytime maximum most likely reaching 19–22 °C under a mild southwesterly flow and partly cloudy skies. Ensemble spreads remain wide because small shifts in cloud timing or wind speed can swing the peak by 2–3 °C, keeping the three leading outcomes nearly equal. Historical May maxima in the city average 16 °C, so current model guidance already reflects above-normal warmth for mid-month. Updated runs expected later today and tomorrow will likely narrow the distribution and shift probabilities ahead of the market’s close.

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 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.Recent short-term forecasts from the Finnish Meteorological Institute and European Centre for Medium-Range Weather Forecasts show Helsinki’s May 18 daytime maximum most likely reaching 19–22 °C under a mild southwesterly flow and partly cloudy skies.
