Midnight sun to light up northern Sweden this week

Treriksröset, Sweden’s northernmost point and where the country borders Norway and Finland, saw its last sunset at 48 minutes past midnight on Sunday. The sun will now not set in the far north of Sweden until July.

The days will now get longer and longer fast. The midnight sun is set to reach Abisko and Karesuando on May 25th, followed by the city of Kiruna on May 28th. It will reach the Arctic Circle just before Midsummer’s Eve and then the days will get darker again.

Midnight sun, as well as polar night, the period of the year where the sun does not rise above the Arctic Circle, are both caused by the axial tilt of the Earth and its revolution around the sun.

In the northern hemisphere the North Pole is tilted towards the sun in summer, so instead of setting, the sun instead moves in a horizontal circle above the horizon. From midsummer, the North Pole gradually turns away from the sun, with the nights getting darker and darker until midwinter.

The same is true in the southern hemisphere, with a six-month time difference – that’s why summer and winter occur at different times in both hemispheres.

Weather alert: ‘Extremely high risk’ of wildfires in parts of Sweden

Sweden’s weather agency warned of an “extreme” risk of forest fires in parts of the country, as helicopters were called in to water bomb a blaze south of Stockholm.

Weather alert: 'Extremely high risk' of wildfires in parts of Sweden

SMHI on Tuesday warned of a high or very high risk of forest fires in south-eastern Sweden, including areas such as Uppsala, Stockholm, Örebro, Norrköping, Jönköping, Karlskrona and Gotland. Locally, the agency described the risk as “extremely high”.

There’s also a high or very high risk of grass fires in parts of Norrland.

On Tuesday morning, firefighters used helicopters to drop water on a forest blaze between Hemfosa and Träsksjön in Haninge municipality south of Stockholm.

It was not known how the fire started. Fire crews were called out to fight it on Monday evening, and by noon on Tuesday most of it had been extinguished. No one was injured.

Fire bans are currently in place in large parts of the Blekinge, Kronoberg, Gotland, Västmanland, Stockholm and Uppsala regions.

The bans are issued by county administrative boards and the rules may vary, but a standard fire ban usually means that you are not allowed to light any fires, other than barbecues in your own garden or at a fixed grill site.
