Recent forecasts from the Finnish Meteorological Institute point to a daytime high near 20°C in Helsinki on June 18, driven by moderate southwesterly flow and limited cloud cover under a building ridge, though ensemble spreads allow for afternoon peaks 1–3°C warmer or cooler depending on boundary-layer mixing and solar insolation near the solstice. Historical June maxima average 17–19°C, but 2026 conditions feature slightly above-normal sea-surface temperatures in the Baltic that can enhance daytime warming when winds remain light. Market-implied odds clustered at 21–23°C capture this forecast uncertainty and the sensitivity of peak readings to exact timing of any diurnal maximum, with lower probabilities for 24°C+ reflecting the low likelihood of strong subsidence or anomalous warm advection in current model guidance. Updated runs from regional ensembles will refine the temperature profile ahead of resolution.

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 Jun '26.
The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day for the Helsinki Vantaa Airport Station, 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 until the first data point for the following date has been published on the resolution source.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent forecasts from the Finnish Meteorological Institute point to a daytime high near 20°C in Helsinki on June 18, driven by moderate southwesterly flow and limited cloud cover under a building ridge, though ensemble spreads allow for afternoon peaks 1–3°C warmer or cooler depending on boundary-layer mixing and solar insolation near the solstice.
