Recent numerical weather prediction ensembles from agencies including the Finnish Meteorological Institute indicate a cooler air mass and increased cloud cover over southern Finland will limit daytime heating on July 21, keeping maximum temperatures near or slightly below the long-term July average of 20–21 °C. Market-implied odds cluster tightly around 15–17 °C because short-range model runs show modest spread driven by uncertain timing of a weak frontal boundary and variable Baltic Sea breeze effects. Persistent marine layer moisture and limited solar insolation under overcast conditions further suppress peaks, while any clearer breaks could briefly allow 18 °C. Traders weigh these variables against historical July extremes and upcoming high-resolution model updates before 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 21 Jul '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 numerical weather prediction ensembles from agencies including the Finnish Meteorological Institute indicate a cooler air mass and increased cloud cover over southern Finland will limit daytime heating on July 21, keeping maximum temperatures near or slightly below the long-term July average of 20–21 °C.
