Vitamin D today

Is there vitamin D in Barcelona today?

In Barcelona the skin makes vitamin D while the UV index reaches 3: today that runs from 11:45 to 15:30. At the best moment about 13 minutes with an average skin type and a quarter of the body uncovered is enough for roughly 1000 IU.

Vitamin D window: 11:45–15:30
In the sun, at the best moment: 13 minutes
Sunrise: 07:58
Sunset: 19:18

Clear-sky figures: cloud lowers the UV index and lengthens the time needed.

Why tomorrow is not the same

The window moves with the height of the sun, which changes every day, and with the ozone column over Barcelona, which varies with the season. It is not one fixed fact about the city: it runs much longer in some months than in others, and at high enough latitudes there are months when it never opens.
