How long in the sun in December?

If you travel anyway, plan your sun session around midday (roughly 11:00 to 15:00), when the UV Index peaks at about 3.6. With about a quarter of your skin bare, a full dose takes around 15 minutes for skin type III at age 30, and about 28 minutes at age 65.
Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 56 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	10 min	19 min	37 min
Type II	12 min	23 min	46 min
Type III	15 min	28 min	56 min
Type IV	22 min	42 min	83 min
Type V	30 min	56 min	1.9 h
Type VI	49 min	93 min	3.1 h

Minutes at midday for about 1,000 IU of vitamin D with a quarter of the body bare, at St. Simons Island, 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.
