September Heatwave Brings Beach Weather to San Juan Capistrano this Weekend

SAN JUAN CAPISTRANO, CA — Are you ready for a September heat wave, Orange County? It will be a perfect beach weekend, just remember to bring your sunscreen.

Tomorrow's ultraviolet index level in the San Juan Capistrano area will be just below 8 according to the National Weather Service.

The reading indicates what the UV exposure is expected to be at noon, when the sun's rays are at their strongest. A high exposure level reading of 7-9 means that a person could be sunburned in 7-8 minutes.

By way of comparison, 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 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.

Ultraviolet radiation is blamed for a host of health problems, including skin cancer and cataracts.

Sunny skies are forecast in this weekend, along with highs of 73 in San Clemente; 75 in Newport Beach and Laguna Beach; 79 in Mission Viejo; 80 in Irvine; 82 in Fullerton and Anaheim; 83 in Yorba Linda, and 88 in San Juan Capistrano.

Temperatures will climb Saturday, then keep climbing until Tuesday, when a downward trend will get underway in several communities.
