This is precisely the picture that I seemed to get when looking at this in depth some time ago. Most meta-reviews highlight a correlation between _number of blistering sunburns_ and melanoma. Not between actual amount of UV exposure. You may think that they’re the same, but they’re not. In fact, the same meta-review was noticing weak anti-correlation between chronic sun exposure and melanoma, I.e. people who work outside shirtless actually have better odds than baseline.
Most risk seems to come from occasional exposure to extremely strong sunlight compared to your day-to-day baseline. Practically speaking, if your skin is able to tan, absorbing as much sunlight as your environment allows for most of the year, with the intrinsic gradual build-up over spring, should be harmless if not even beneficial.
Of course, this highly depends on your genetics and your location. Avoid sunbathing around the equator regardless. And if you’re physically unable to tan, as some people do, then this might not be true either. I couldn’t determine that as easily.
