The student cities of Lund and Uppsala, which usually attract many of the most dedicated Walpurgis Night revellers, can for example count on 15 and 14 degrees respectively in the afternoon and a sun that at least peeks out from behind the clouds according to the long-term forecast.
On May 1st, it also looks fairly hopeful, says Therese Fougman, meteorologist at SMHI.
But she simultaneously has a big caveat: The forecast is still uncertain.
We have low-pressure systems around us next week and then it depends on what path they take as they move in over us in Scandinavia.
No heat shock is to be expected, nor the worst possible weather.
There is no clear high-pressure system and there are no well-defined low-pressure systems coming in in a row, says Therese Fougman.
So far, the forecasts for Walpurgis Night and May 1st should be taken with a pinch of salt, but towards the coming weekend they should become a bit more reliable.
