Can pickled herring be eaten outdoors or indoors on Midsummer's Eve? Yes, it depends on when a low-pressure system with rain moves in over the country, and where you plan to celebrate, of course. But take a raincoat and be prepared for showers, even if the sun is shining.
Midsummer's Eve can be warm and high-pressure dominated, but it can also be rainy, according to the Met Office.
The forecast is highly uncertain as it depends on when a low-pressure wave lying southwest of Sweden grows and moves in over the country. The low-pressure wave has not yet made up its mind, but it's coming, says Angelica Lundberg, meteorologist at the Met Office.
The best chance of a sunny Midsummer celebration with higher temperatures can be found on the west coast, Skåne, and Småland. There, according to the Met Office, it will be sunny with 20-23 degrees Celsius. However, during the night leading up to Midsummer's Day, the low-pressure system from the southwest will bring rain and lower temperatures. The low-pressure system will move north over the rest of the country on Saturday.
In northern Sweden, the weather on Midsummer's Eve will be like it is now, around 15 degrees Celsius with scattered showers. A bit warmer towards the coast, says Angelica Lundberg.
But since the forecast remains uncertain, there is still hope for sun and warmth over the weekend.
