Burn Warning: UV Index of 11 Expected

Wednesday will bring a chart-topping UV Index of 11 to San Marino and surrounding areas. This means a fair-skinned person could develop sunburn in under four minutes if not protected.

The sun's rays will be especially strong Wednesday in San Marino and the Los Angeles area. The ultraviolet index level is forecasted to be 11, according to the National Weather Service.

The UV Index is measured on a scale of one to 11+, so this forecast is about as high as you can get. The reading indicates what the UV exposure is expected to be at noon, when the sun's rays are at their strongest.

Here's a look at the UV Index Scale:

  • A reading of 0-2 indicates a minimal exposure level, and very fair-skinned people could become sunburned in 30 minutes if not properly protected.
  • A reading of 3-4 is considered a low exposure level, reducing the danger
    range for those with fair complexions to 15-20 minutes if not protected.
  • A moderate exposure level of 5-6 indicates that a person with a fair
    complexion could be safe from sun burn for 10-12 minutes, unless protected.
  • A high exposure level reading of 7-9 means that a person could be sunburned in 7-8 minutes.
  • A very high exposure level reading of 10, or greater, means a fair-skinned person could suffer a sunburn in about four minutes if not protected.
