The maximum UV Index range is 11+.
The UV Index, developed by the World Health Organization (WHO), is a measure of the intensity of ultraviolet (UV) radiation from the sun at a particular place and time. This index helps inform people about the potential for sun damage and the need for sun protection. The scale ranges from 0 (no UV radiation, typically at night) upwards. A UV Index of 3 or higher signifies that sun protection is necessary for the general population. Values exceeding 11 are considered extreme.
Here's a breakdown:
- UV Index 0: Minimal UV radiation; no sun protection needed.
- UV Index 3-7: Moderate to High UV radiation; sun protection recommended (sunscreen, hats, sunglasses).
- UV Index 8-10: Very High UV radiation; extra precautions needed to avoid sunburn and skin damage.
- UV Index 11+: Extreme UV radiation; avoid sun exposure during peak hours and take all necessary precautions.
It is important to note that the UV Index can exceed 11 in certain geographical locations, at high altitudes, and during specific times of the year when the sun's rays are most intense.
