Memorial Day mishaps happen. Make sure sunburn isn't one of them. Check the UV Index.

Updated: Jun 1, 2023

It's a holiday weekend and the weather looks settled in southern California - quite warm with lots of sunshine. Perfect conditions for enjoying the great outdoors.

But whether it's 60F or 90F, there is still a high risk of sunburn at this time of year.

The issue is not how hot it is, but how high the Ultraviolet (UV) levels are. Sunburn occurs when your skin is overexposed to UV radiation from the sun's rays.

UV levels vary with the seasons and time of day, but when the UV index is three or above, we need to protect our skin and eyes. The UV levels are often three or more, even on cool or cloudy days, and the rays from the sun can be strong enough to damage our skin and eyes.

The UV Index shows how much ultraviolet radiation is reaching us from the sun and how careful we need to be. Los Angeles is forecast to hit a “Very High” risk of 8.7 today on the UV Index.

Even the partly cloudy conditions of 'May Gray' and 'June Gloom' at this time of year will not block out the harmful rays of the sun. A cool breeze can be misleading, especially in coastal areas where there is additional reflection from the ocean.

So it is important to know what the UV index is going to be throughout the day where you are. You can check the UV Index for your area here.

Higher temperatures do not increase the risk of sunburn, but if it is warmer, we are more likely to be outdoors and less covered up. Which means you should make sure to adopt sun protection measures such as wearing a hat, long sleeves, sunshades, and other sun protective clothing.

Make sure to apply a sunscreen with sun protection factor (SPF) 30+ and broad spectrum protection which will protect your skin from both UVA and UVB waves. Some sunscreens only protect against UVB rays, the ultraviolet rays that cause sunburn. Coral Sure Sunscreen protects against both and helps prevent premature aging, wrinkles, and some skin cancers.
