UV Index Program
Interpretation of the UV Index
The UV index is included in Environment Canada's weather forecasts whenever
it is expected to reach 3 (moderate category) or more. This table outlines
the sun protection actions recommended at different levels of the UV index.
Remember that the amount of UV you receive depends on both the strength of
the sun's rays (UV Index) and the amount of time you spend in the sun.

against both UV-A and UV-B rays. Apply generously before going outside and
reapply often, especially after swimming or exercise. |
