NWS: Sun's Rays to Strengthen In Area

The sun’s ultraviolet index level in the Hermosa Beach area is expected to reach 10 on Tuesday, according to the National Weather Service.

An exposure level reading of 10 or greater indicates that a fair-skinned person could suffer sunburn in about four minutes if not protected by sunblock or clothing, for example.

The level 10 exposure is expected to hit around noon, when the sun’s rays are at their strongest, according to meteorologists. 

When ultraviolet index levels are measured, a reading of 0-2 indicates a minimal exposure level. Very fair-skinned people could become sunburned in about 30 minutes if not properly protected.

A reading of 3-4 is considered a low exposure level, reducing the potential of sunburn for those with fair complexions to 15 to 20 minutes if not protected.

A moderate exposure level of 5-6 indicates that a person with a fair complexion could be safe from sunburn for 10 to 12 minutes, unless protected.

A high exposure level reading of 7-9 means that a person could be sunburned in about seven to eight minutes. A level of 10 or greater is classified as "very high."
