Current UV Index and Hourly UV Index Forecast

What is the UV Index?

The UV Index is a measurement scale used to indicate the intensity of ultraviolet (UV) radiation from the sun at a particular place and time. The values range from 0 to 11 and above. The higher the index value, the greater the potential for damage to the skin and eyes, and the less time it takes for harm to occur.

How is the UV Index measured?

The UV Index is calculated using measurements of UV radiation, particularly UVB and UVA rays. These measurements are typically made by sensors on satellites and ground-based instruments. These values are then weighted based on the potential harm each type of radiation can cause to human skin and are combined to provide a single index value.

Can the UV Index affect my skin?

Yes, a high UV Index indicates that the ultraviolet radiation is strong enough to cause harm to your skin in a short amount of time. This can lead to sunburn, premature aging of the skin, and an increased risk of skin cancer. It's important to take protective measures such as wearing sunscreen, sunglasses, and protective clothing when the UV Index is high.

What are the different UV Index levels and what do they mean?

The UV Index is a scale that provides an indicator of the expected risk of overexposure to the sun. It is a way to quantify the strength of sunburn-producing ultraviolet (UV) radiation at a particular place and time. The scale goes from 0 to 11+, where higher numbers indicate a higher risk of overexposure to UV radiation.
