Today Saturday has been National Nature Day, and lovers of the outdoors have been treated to warm and clear weather in which to picnic or hike. After two weeks of almost non-stop rain, a high pressure front has intensified over Finland, making this weekend a drier one.
The forecasts for the next month show a possibility of a warm start to autumn – though long-term predictions are notoriously uncertain. But weather maps for the next few weeks also show warmer temperatures than Finns are used to in September, both in the north and south.
“By the time we’ll be into the second week of September, it’ll get a little colder,” meteorologist Matti Huutonen says. “Colder air will be released in the north and temperatures will fall to their usual autumn lows.”
Clear skies bring cold nights
This last weekend of August will be clear or even sunny in many parts of the country.
“This is a sure-fire sign of colder nights to come,” Huutonen says. “The first sub-zero temperatures have already been measured in the north, and frost may appear as far south as Central Finland.”
Warmth is still expected before the chills, as Sunday will be warmer even than Saturday.
“The high pressure will stay over Finland and tighten its grip,” Huutonen continues. “We’ll be seeing highs of over 15 degrees the whole country over, and sunshine might come through nicely too.”
