What UV Index is the Optimal Level for Tanning?


The UV index indicates how powerful the sun is in a particular area and time. And depending on the climate and type of skin, certain UV indexes are more suitable for tanning.

Gaining a better comprehension of the UV index. Its importance and how to use it to get a great tan are all explained here.

Knowing the UV index can help you make decisions on how to best protect your skin and get the perfect tan.

Understanding the UV Index

The UV index, also referred to as UVI. Is a measure of the intensity of ultraviolet radiation at a given location and time. It is an indicator of the risk of sunburn associated with the level of exposure to the sun’s rays.

The amount of Ultraviolet Index (UVI) fluctuates depending on the climate and time of year, and was devised by Canadian researchers in the 1970s.

The scale ranges from 0 to 11+ and is frequently utilized by meteorologists when giving out information to the public, so it may have been seen before.

At night, a scale of 0 or near 0 is typical, while 1-2 is considered to be low, 3-5 is moderate, 6-7 is high, 8-10 is very high, and 11 or higher is extreme.

In winter, especially on very cloudy days, low levels of sunlight can be anticipated. On cloudy days in spring or autumn, moderate levels are usually seen. 

High levels of sunlight can be expected on sunny days during those two seasons. Very high levels of sunlight occur on very sunny summer days.

And extreme levels are typically experienced in tropical zones and/or at high altitudes on very sunny days.

Which Index Should I Use to Tan?

In order to get a tan, exposure to both UVA and UVB rays is necessary. UVA darkens the pigment cells already present in your skin, while UVB stimulates the production of additional pigment cells.

The ideal index for tanning will vary depending on where you are, the altitude, and your skin type.

As the UVI increases, the speed at which your skin can be damaged by the sun increases. To take advantage of your skin’s natural defense system. 

It is recommended to use a tan accelerating body lotion to promote the tanning process. This way, your skin can create more pigment cells without the need for UVB radiation.

In addition, you’ll be more likely to get a tan with a lower UV index. And you won’t have to spend so much time in the sun. Avoiding the potential damage the sun’s rays can cause.

The National Institute for Health and Care Excellence suggests. That people should receive an exposure to sunlight of at least 15-30 minutes daily between 11 a.m. And 3 p.m. from March to October. While avoiding the sun during the hours of 10am and 3pm in the summer.

The UV index between 3 and 7 is considered to be a moderate to high level. And is the ideal range for most skin types to achieve a tan. 

To be more cautious, it is best to tan outside when the UV index is on the lower end of the scale. 

For those who want to tan faster and darker, a higher UV index is recommended; for more information, please read the article on how to tan faster and darker outside.

When spending extended periods of time outdoors, it is highly recommended to wear a broad-spectrum sunscreen to protect from the sun’s rays.

It is noteworthy that temperature does not have an impact on tanning, contrary to what some may think. To find out more about this, read our article – how hot does it need to be to tan?

What Type of Protection is Required?

No matter the weather, sunscreen should be worn daily, but it is especially important to use it during the summer months when the sun’s rays can penetrate even through clouds.

Protecting the most sensitive areas such as your eyes, lips, and scalp is essential. Wearing sunglasses, applying lip balm, and using hair styling products with at least 30 SPF protection are all important steps to take.

Only a small portion (3% for SPF 30 and 2% for SPF 50) of UVB rays can penetrate the skin when wearing sunscreen. Although sunscreen can provide some protection, 

It should be reapplied regularly (every 2 hours) while in the sun to ensure continuous coverage. To learn more about this topic, please read our article on whether or not you can tan with sunscreen.

UV indexes between 6 and 7 are deemed high, typically occurring on sunny days during spring or autumn. It is important to apply sunscreen with an SPF of 30 or higher, even on cloudy days.


The UV Index (UVI) is an important measure of the intensity of ultraviolet radiation at a given location and time. 

It is an indicator of the risk of sunburn associated with the level of exposure to the sun’s rays. The scale ranges from 0 to 11+, and is frequently utilized by meteorologists when giving out information to the public.
