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 3.1. With about a quarter of your skin bare, a full dose takes around 17 minutes for skin type III at age 30, and about 32 minutes at age 65.
Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 65 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	11 min	22 min	43 min
Type II	14 min	27 min	54 min
Type III	17 min	32 min	65 min
Type IV	26 min	48 min	97 min
Type V	34 min	65 min	2.2 h
Type VI	57 min	1.8 h	3.6 h

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