How long in the sun in June?

Plan your sun session around midday (roughly 11:00 to 15:00), when the UV Index peaks at about 5.7. With about a quarter of your skin bare, a full dose takes around 9 minutes for skin type III at age 30, and about 18 minutes at age 65.
Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 35 minutes of midday sun, so cover up, find shade and use SPF 30+ on skin that stays out.
Water, sand and light surfaces reflect UV, so at the beach you get a little more sun than the number suggests, for the good and the bad.

Skin type	Full dose, age 30	Full dose, age 65	Time to burn
Type I	6 min	12 min	23 min
Type II	8 min	15 min	29 min
Type III	9 min	18 min	35 min
Type IV	14 min	26 min	53 min
Type V	19 min	35 min	70 min
Type VI	31 min	58 min	1.9 h

Minutes at midday for about 1,000 IU of vitamin D with a quarter of the body bare, at Nadi, the median coastal place. Time to burn is the time to reach one minimal erythemal dose and does not depend on age. A rough planning guide, not medical advice.
