Vitamin D in Myanmar in July: sun, UV and what to expect
Bad weather Bad weather: it rains on about 30 days in July (rainy or monsoon season), so sun is hard to count on and a beach stay is not recommended.

How long in the sun in July?
- If you travel anyway, plan your sun session around midday (roughly 11:00 to 15:00), when the UV Index peaks at about 5.9. With about a quarter of your skin bare, a full dose takes around 9 minutes for skin type III at age 30, and about 17 minutes at age 65.
- Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 34 minutes of midday sun, so cover up, find shade and use SPF 30+ on skin that stays out.
- On clear days the UV Index reaches about 9.0, which is very strong. Keep sessions short and protect the rest of the day.
- 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 | 9 min | 17 min | 34 min |

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