**Forecast models show moderate uncertainty in peak temperatures for Helsinki on June 18, with consensus highs clustered near 21–23 °C driving the tight market spread.** Recent runs from European and global ensembles indicate a mix of partly cloudy skies, light southerly flow, and limited daytime heating under June’s long daylight hours, tempered by possible on-and-off showers that could cap the maximum. Historical June averages near 18–19 °C provide context, but current synoptic patterns favor a modest positive anomaly. Key variables differentiating the leading outcomes include exact cloud-cover timing, boundary-layer mixing, and any late-day clearing that could add 1–2 °C. Updated model guidance and official Finnish Meteorological Institute briefings over the next 48 hours will likely narrow the distribution 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.**Forecast models show moderate uncertainty in peak temperatures for Helsinki on June 18, with consensus highs clustered near 21–23 °C driving the tight market spread.** Recent runs from European and global ensembles indicate a mix of partly cloudy skies, light southerly flow, and limited daytime heating under June’s long daylight hours, tempered by possible on-and-off showers that could cap the maximum.
