“At this time of year the spring has usually, according to the ‘normal timetable’, established itself along the Skåne coasts. But thespring has not arrived and it is now around a week late,” SMHI wrote in a statement.
According to the agency’s definition of spring, the new season arrives when the daily average temperature tops zero degrees Celsius for seven consecutive days.
While warmer temperatures have been recorded in several parts of Sweden in recent days, with Stockholm enjoying above freezing temperatures and sunny weather, the arrival of spring is still yet to be formally announced.
“March has at least given some spring temperatures,” SMHI concluded.
At Lake Tysslingen near Örebro in central Sweden however, bird watchers have reported the precipitant arrival of a flock of whooper swans, traditionally taken to mean that spring is indeed imminent.
The local Tysslingen Foundation has taken this to be a clear indication of spring, a week earlier than last year.
Lake Tysslingen is Europe’s largest gathering place for whooping swans with thousands arriving each year and the foundation is gearing up to formally welcome their feathered visitors with its annual swan festival opening on March 18th.
