UV Index Scale Explained for Long Beach
The UV index runs from 1 to 11 and above. A reading of 1 to 2 is low and most people need no protection. From 3 to 5 you should cover up or use SPF. Anything above 6 is high or extreme, which means unprotected fair skin can begin reddening in well under 30 minutes. On a typical summer afternoon in Long Beach, the reading sits around 12, which puts everyone outside the extreme risk band. Your skin type matters too: your skin type determines how quickly you burn at any given UV. Kids playing outside for an hour at UV 6 with a hat and SPF 30 are well protected, so this is manageable with simple habits.
How to Protect Your Skin in Long Beach
At UV 3 to 5, SPF 15 broad-spectrum is the baseline. At UV 6 to 7, move to SPF 30. From 8 upward, SPF 30 plus a hat and sunglasses become the standard combination, with SPF 50 for extended outdoor time. One Long Beach-specific point: water and wet sand reflect 15 to 25 percent of UV back up onto your face, so the underside of your jaw and chin burn faster than your shoulders. Reapply every two hours of direct sun and after swimming. One counterintuitive fact: car and home windows block UV-B but most pass UV-A, which still ages skin and contributes to skin cancer risk.

Spotting Melanoma Early with ABCDE
The ABCDE rule is the simplest way to check a mole at home. Asymmetry: one half does not match the other. Border: irregular or fuzzy edges. Color: more than one shade. Diameter: larger than 6mm, about the size of a pencil eraser. Evolving: any recent change in size, shape, or feel. Tracking daily UV in Long Beach matters because skin damage is cumulative, and one bad burn in childhood roughly doubles lifetime melanoma risk.
