Solar UVI is a simple UV Index viewer showing you the current UV index for your location and the forecast for the next day.
Excessive exposure to Ultraviolet radiation can have severe effects on your health, from sunburns, eye damage, skin aging to the big oh-no: skin cancer. That's why it's important to take measures to protect yourself and knowing the current radiation level is the first step to preventing harm.
Please note that there are no correlation between UV index and temperature. So, even the temperature is low, it doesn't mean the UV index is low as well, and vice versa.
