why do we get sunburnt at a faster rate at different periods throughout the day?

Question

E.g. I always heard that you should avoid sitting in the sun between 11 and 15 pm. But any time other than that is okay.

Answer 1

Tom Skilling, famous American meteorologist, says that the sun’s position and distance from earth means that from 11am to 2pm in summer is peak tanning times. It takes twice as long to get the same tan at 3pm as it does at noon.
The same goes for the calendar. September tans take longer than a June tan, when the sun is closer.
