What does the UV index mean?
The levels of UV radiation and therefore the values of the index vary throughout the day. In reporting the UVI, most emphasis is placed on the maximum UV level on a given day. This occurs during the four-hour period around solar noon. Depending on geographical location and whether daylight saving time is applied, solar noon takes place between noon and 2 p.m. The media usually present a forecast of the maximum UV level for the following day.
How can the UV index help me to protect myself?
Most people are used to adjusting their daily plans and choice of clothing to the weather forecast, especially to temperature predictions. Analogous to the temperature scale, the UVI gives an indication of the level of UV radiation and the potential danger of sun exposure. It can help individuals make healthy choices.
