Solar ultraviolet radiation (UVR) has the potential to cause biological harm to humans. Intensity of solar UVR at the Earth’s surface depends on several factors, such as total column ozone and cloud cover, and temporal trends are usually dependent on season and time of day.
Understanding such patterns helps inform the development of sun protection awareness information for the public. Here, solar erythemal (sunburning) UVR levels were analysed for three populated coastal sites in South Africa and Reunion Island to determine seasonal and diurnal trends. These trends were then discussed in light of tailoring appropriate public health messages.
