How long in the sun in November?

If you travel anyway, plan your sun session around midday (roughly 11:00 to 15:00), when the UV Index peaks at about 2.8. With about a quarter of your skin bare, a full dose takes around 19 minutes for skin type III at age 30, and about 36 minutes at age 65.
Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 71 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	13 min	24 min	48 min
Type II	16 min	30 min	60 min
Type III	19 min	36 min	71 min
Type IV	29 min	54 min	1.8 h
Type V	38 min	71 min	2.4 h
Type VI	63 min	2.0 h	4.0 h

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