In central Europe some countries have recorded the highest temperatures ever. In Britain people appear to die every day for reasons connected more or less directly to the heatwave.
In Finland we have some sun, for some of the time, on some days, and a whole lot of wind on most days. Interspersed with this we have rainstorms.
Finnish sunbathing therefore requires a different approach, and different clothing, to sunbathing in the rest of Europe.
