Vitamin D in Panama in April: sun, UV and what to expect
Bad weather Bad weather: it rains on about 21 days in April (rainy or monsoon season), so sun is hard to count on and a beach stay is not recommended.

The country rating is for a typical beach, but some places in Panama still work in April: Pedasí (excellent), Isla Contadora (excellent), Santa Catalina (excellent).
How long in the sun in April?
- If you travel anyway, plan your sun session around midday (roughly 11:00 to 15:00), when the UV Index peaks at about 9.0. With about a quarter of your skin bare, a full dose takes around 6 minutes for skin type III at age 30, and about 11 minutes at age 65.
- Stop well before your skin turns pink. At this UV level skin type III can start to burn after about 22 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 9.4, 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.

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