I believe mid day sun is the best for producing vitamin d though.

Correct, the atmosphere will block the rays that cause vitamin d production so the best time to be exposed is around noon +/- a few hours when the sun is above you

Australasia has it particularly bad. I have fair skin — 20 min in the sun on a boat with no sunscreen a few summers ago and I had a series of doctors visits over the next week to treat the, quite literally, blistering sunburn.
Being pale and then going for 4 hours at noon to the beach is trouble, build up to it or wear clothing to shade you. If you are naturally pasty and live in the tropics.. mmm . You are in trouble.
