What is the UV Index Today?

What’s the current UV Index rating? What does the UV Index show for tomorrow? You can use this handy tool to check the UV levels in your area, so you can plan your outdoor activities accordingly. It’s important to be aware of the UV Index rating when venturing outside. On a particular day, you may need to take extra precautions to protect your skin — and without the UV Index, you would be unaware of the possible damage to your skin. 

What is the UV Index & What Does it Mean? 

The UV Index (UVI) measures the level of UV radiation in a specific area. The purpose of the UVI is to alert people about when they need to be extra cautious about sun exposure. People are used to planning their daily activities around the weather; the UVI works similarly. Chances are you would adjust your plans if there’s rain in the forecast. You should do the same if the UV radiation level is high to extreme. Enter your location in the box to the right to find the current UV Index.

What Are the UV Index Levels? 

The UVI ranges from 1 to 11+. Here’s a quick look at what each of these levels means in terms of the level of UV radiation: 

  • 1,2: Low 
  • 3,4,5: Moderate 
  • 6,7: High 
  • 8,9,10: Very High
  • 11+: Extreme

Why is the UV Index Important When Considering Health? 

UV rays are dangerous year-round, even during the winter. There are two types of UV light that are proven to contribute to the risk of developing skin cancer: UVB and UVA rays. UVB (Ultraviolet B) rays have a shorter wavelength than UVA (Ultraviolet A) rays and are associated with skin burning. UVA rays have a longer wavelength and are associated with skin aging. Although they differ, both are harmful to your skin. 

When the UVI reads 0-2, you’ll want to wear sunscreen, but you can safely enjoy being outside. A UVI rating of 3-7 is a slightly different story; wear a hat, sunscreen, and cover up as much as possible. Seeking shade during midday hours is also recommended. If the UVI rating is 8 and above, simply avoid being outside during midday hours. If you must be outdoors, seek shade, wear sunscreen, and cover up.
