The IPMA has also placed the islands of São Miguel (eastern group of the Azores), Faial and Terceira (central group of the Azores) and Flores (western group) at high risk of exposure to UV radiation.

For regions with very high risk, the IPMA advises the use of sunglasses with UV filter, a hat, t-shirt, parasol, sunscreen and avoid exposing children to the sun.

The calculation is based on values ​​observed at 13:00 each day for air temperature, relative humidity, wind speed and the amount of precipitation in the last 24 hours.
