From January to February, the UV levels are moderate (3-5), allowing for longer safe exposure times of about 30 minutes.

September marks a slight decline in UV intensity but remains very high at 8. In contrast, October through December sees a return to moderate levels, with burn times reverting to 25-30 minutes.
