No, because the sun at low angles passes so much atmosphere, that filters most out.

The exposure angle of your body also has a effect, but much weaker.



Today in Stockholm the UV index peaked at 6.3. And it is just a few days after the summer solstice, and the sky was largely clear today.

(Yet I can feel that I got slight sunburn being out for about 15 minutes today. So you still need to be careful.)

In winter the UV index might often peak at 1-2 on a clear day.
