Not all sun is equal. The UV index tells you how strong the rays are, and that decides whether you’re gonna tan or fry.
What UV index is best for tanning, when to go out, and when to stay in the shade.
What UV is good for tanning?
Moderate UV (around 3 to 5) is usually the sweet spot. Enough to get color without nuking your skin. Low UV (1 or 2) means you can stay out longer but you’ll tan slower. High UV (6+) means shorter sessions and solid SPF. We break it down in Understanding UV Index: Your Guide to Safe Tanning.
UV 3 to 5 is usually the sweet spot for building color without burning. Avoid peak midday when the index is highest. Reapply sunscreen every two hours, and wear a hat and sunglasses when the index is 6 or above.
When to go out
Early morning or late afternoon = lower UV, longer safe exposure. Midday = strongest UV. If you’re fair, avoid 11 to 3. If you’re darker, you have more room but still don’t overdo it.
