If you don't want to wear sunscreen at all, you can use UV Index calculators like this, which take into account the hourly UV index, location, and your skin type to calculate safe sun exposure times: https://sunburnmap.com/ https://sunburnmap.com/ Just be cautious because the time still stacks up - eg. walking to and from the beach in the morning/afternoon.
