Finland’s unusually sunny and mild run is about to give way to a colder, more unsettled pattern, with forecasters warning that rain, sleet and even snow could return to parts of the country, including the south. According to Foreca the shift is expected to become more pronounced from midweek, with stronger northwest winds, falling temperatures and a risk of hazardous driving conditions.
A high-pressure system has kept much of Finland dry and bright for several days, helping temperatures climb well above seasonal norms in places. But that pattern is weakening, and a cooler flow from the northwest is set to bring cloudier skies, scattered showers and more springlike volatility.
Forecasters say Monday and Tuesday should still offer the calmest conditions, with sunshine dominating and daytime temperatures mostly in the 8-15 C range.
By Wednesday, wind gusts are expected to strengthen across the country, and in Lapland they could become strong enough to cause localized damage.
As the colder air spreads southward, precipitation will become more widespread and more mixed in form. In northern areas, snow is likely at times, while elsewhere showers may fall as rain, sleet or a combination, especially overnight and in the early morning.
Temperatures are expected to drop further toward the end of the week, with many parts of the country struggling to rise above 10 C and nighttime frost becoming common nationwide.
Forecasters also warn that road conditions could turn slippery at times, particularly when showers coincide with low temperatures and weak visibility.
The longer-range outlook suggests the colder trend may persist into the May Day holiday week, especially in southern and western Finland, where average temperatures are projected to be below normal. In eastern and northern areas, temperatures are expected to stay closer to seasonal levels, but precipitation remains likely.
That means Finland could face a mixed start to May, with the possibility of rain, sleet and snow still lingering in the forecast. Meteorologists say the exact weather for May Day remains uncertain, but the broad signal points to a cooler and more unsettled period than the recent spell of spring sunshine.
