Hey Zee

When traveling in the Caribbean last year I used factor 25 on my face and neck and factor 10 on body until I was tanned. These days I am more careful and would recommend the use of at least 15 on your body and 30 on your face. You must reapply every time you take a swim. Anywhere near Equator you should use factor 20 or higher. You might find the weather in Durban disappointing; it has some of the lowest sunshine figures in Southern Africa. It is hot, humid, overcast and the rainy season. The other places you mention will need sun protection, in which case I would also suggest 30+, unless you are purposely trying to achieve a specific tan level. Don’t be foolish and ruin your trip with severe SUN BURN.
