It largely depends on two factors: the UV index in your location at a specific time and your skin type.
The UV index or ultra violet index is an international standard measurement of the sunburning UV in a particular place at a particular time.
0-2 Low, 60 minutes to sunburn
3-5 Medium, 45 minutes to sunburn
6-7 High, 30 minutes to sunburn
8-10 Very High, 10 minutes to sunburn
11+ Extreme, less than 10 minutes to sunburn
The UV index and the guide above is helpful up to a point, but if you are a skin type which is more susceptible to sunburn it makes sense to take a more conservative approach if you know you are going to be outdoors for aprolonged period irrespective of the UV index rating for the day.
Skin types were rated 1-6 by Thomas Fitzpatrick in the1970s, and is still used today as the international standard. People with skin type 1 and 2 are most susceptible to sunburn and skincancer related issues.
A person with type 1 or 2 skin has characteristics which include pale skin, blue eyes, red or blonde hair, freckles and skin that rarely tans when exposed to the sun. If you fit that description you should proactively protect your skin from the sun and UV exposure regardless of the UV index.
Sunburn is caused by UV light overexposure. Dermatologists always recommend UPF50+ sun protective clothing to preventsun burn and skincancer related issues.

Your skin is your largest organ and has a long memory. Sun exposure and ultraviolet (UV) damage is cumulative throughout your life. Research shows that sun damage contributes to more than 90% of wrinkles, brown spots, premature skin ageing as well as precancerous and cancerous skin lesions.
Limiting sun exposure is very important, as the UV rays cause the most damage to the skin. It often takes many years and sometimes decades for the effects to become visible.
