25°C seems to be quite nice in comparison to the rest of Europe :-D
I remember being on a rowing trip on the Lofotes, something like 2000-2005. It was a very hot summer, around 30°C, so we decided to jump in the water. Bad call. The polar see does not warm as much as the air.
Looks like Smallsteps had a lot of fun. I hope you did, too, despite the sun :D
It really was very cold in the water - 14C by the shore, about 12C a bit further out - that is chilly.
It was a lot of fun. Even with the sun. Met up with the friends and chilled with them too :)
That is indeed chilly. Glad you found the friends and had a good time! "Just and necessary", as a friend always says.
