Not as warm as in Western Canada, but many days above 25°C (ca 80°F) is too much for many Finns, since we don't have AC except from in cars and grocery stores and a few other places. Our society is built for long, cold winters. We have triple glass windows and stable temperature indoors of between 20-24°C in every single house, even if it's -30°C outside. https://www.helsinkitimes.fi/finland/finland-news/domestic/19537-hot-summer-to-continue-in-finland-need-for-emergency-care-has-already-risen.html
