How long in the sun in August?
- Plan your sun session around midday (roughly 11:00 to 15:00), when the UV Index peaks at about 7.7. With about a quarter of your skin bare, a full dose takes around 7 minutes for skin type III at age 30, and about 13 minutes at age 65.
- Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 26 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.

| Type III | 7 min | 13 min | 26 min |
