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 5.4. With about a quarter of your skin bare, a full dose takes around 10 minutes for skin type III at age 30, and about 19 minutes at age 65.
Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 37 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	7 min	12 min	25 min
Type II	8 min	15 min	31 min
Type III	10 min	19 min	37 min
Type IV	15 min	28 min	56 min
Type V	20 min	37 min	74 min
Type VI	33 min	62 min	2.1 h

Minutes at midday for about 1,000 IU of vitamin D with a quarter of the body bare, at Port Vila, 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.
