Latest numerical weather prediction models from sources including the European Centre for Medium-Range Weather Forecasts show Helsinki maximum temperatures on June 30 clustered near 25–27 °C under a building high-pressure ridge that favors clear skies and modest southerly flow. This setup supports strong daytime solar heating during peak daylight hours, yet modest uncertainty remains from possible afternoon cloud development or slight shifts in the surface wind field that could cap or boost readings by 1–2 °C. The tightly matched market probabilities for 26 °C and 27 °C reflect this narrow forecast spread and the sensitivity of the daily maximum to small changes in boundary-layer conditions. Updated high-resolution runs and official Finnish Meteorological Institute guidance expected in the next 24–48 hours will likely refine the outcome ahead of the noon UTC resolution window.

This market will resolve to the temperature range that contains the highest temperature recorded at the Helsinki Vantaa Airport Station in degrees Celsius on 30 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.Latest numerical weather prediction models from sources including the European Centre for Medium-Range Weather Forecasts show Helsinki maximum temperatures on June 30 clustered near 25–27 °C under a building high-pressure ridge that favors clear skies and modest southerly flow.
