In the news today in Finland is told that a Spring ozone hole similar to that usual over Antarctica has been detected today for the first time over the Arctic. Data is from sounding in the north of Finland. News says: 90% of stratospheric ozone reduction at an altitude of 18 km. Current ozone column of 271 DU compared to the usual 416 DU at this location and time of the year. I found the news only in Finnish, published a bit over an hour ago.

Anyway, current UV-Index and 2-days forecast is available at https://en.ilmatieteenlaitos.fi/uv-index. This page covers the whole planet and has links to detailed maps for different regions.
