Finland will experience widespread rainfall and below-average temperatures over the next 24 hours, as low pressure dominates weather patterns across the country. Forecasts suggest rain may reach up to 60 millimetres per day, especially in central regions.
Aleksi Lohtander, meteorologist at Yle, said rainfall would intensify through the afternoon and evening. “We expect up to 50–60 millimetres of rain within 24 hours,” he said.
Temperatures remain low, hovering between 10 and 15 degrees Celsius nationwide. No heatwave conditions are forecast.
Rain will begin to ease by Wednesday as the low-pressure area shifts eastward. Temporary dry spells are forecast for Thursday and Friday, but temperatures will remain stable.
“Conditions may improve briefly, but more rain is expected by Sunday,” said Lohtander.
Foreca’s long-range forecast suggests the wet and cool conditions will persist into early July. According to Sara Salonen, meteorologist at Foreca, the current pattern appears entrenched.
“The weather remains unstable and cooler than average across Finland and much of northern Europe until mid-July,” Salonen said.
Rainfall totals from Monday to Wednesday could exceed 50 millimetres in central regions. Most areas are forecast to receive 10 to 30 millimetres, with isolated downpours. Rainfall is expected across southern, central, and parts of western Lapland.
Temperatures will range from 12 to 18 degrees Celsius in most areas. Some southern regions may reach near 20 degrees during sunnier spells, while northern areas could see daytime highs below 10 degrees. Night-time frosts remain possible in Lapland, with potential ground frost in other northern areas.
Next week is not expected to bring significant change. Forecasters predict continued rain and cooler temperatures.
There are indications of a possible shift around mid-July. Models suggest normal conditions may resume by the week beginning 7 July, though confidence in long-range rainfall forecasts is limited.
“A high-pressure system might build over eastern Europe, diverting low-pressure systems either north or south of Finland,” said Salonen. “It remains uncertain whether Finland will fall under dry high-pressure or remain in cloudy and wet conditions.”
By the second half of July, forecasts increasingly point to reduced rainfall and a warming trend. Some data shows a higher probability of high pressure strengthening over northern Europe, potentially ending the prolonged wet spell.
