Shocking UV levels outdoors

Today’s sky overhead was a mix of fog and occasional Sun peeking through. I used SHealth to take two UV measurements: One when the Sun was fully showing, and a second when there was fog covering it.

The results: When the Sun was fully showing the UV level was registered as “extreme”. Whoa!
When the Sun was covered with fog it still registered as “high”.

So even going outdoors when it seems like there’s a protective layer of fog between you and the Sun doesn’t necessarily mean that the UV exposure is not dangerously high. And if there’s any Sun poking through then the level jumps to extreme. Yikes!
