The UV Index
Environment Canada developed the UV Index to inform Canadians about the strength of the sun's ultraviolet (UV) rays. UV rays can cause sunburns, eye cataracts, skin aging and skin cancer. The higher the UV Index number, the stronger the sun's rays, and the greater the need to take precautions.
The table below outlines the sun protection actions recommended at different levels of the UV Index.
|UV Index||Description||Sun Protection Actions|
Sun Protection Tips
- The amount of UV you receive depends on both the strenth of the sun's rays (measured by the UV Index) and the amount of time you spend in the sun. Reduce your time in the sun - seek shade, particularly between 11 a.m. and 3 p.m. from April to September.
- Cover-up, wear a broad-brimmed hat, a shirt with long sleeves and wrap-around sun-glasses or one with side shields.
- Use sunscreen - with a sun protection factor (SPF) of 15 or higher, with both UVA and UVB protection. Apply generously before going outside, and reapply often, especially after swimming or exercise.
- Listen for Environment Canada's UV Index - it's included in your local weather forecast whenever it is forecast to reach 3 (moderate) or more that day.

The UV index measures the strength of the sun's rays. The higher the Index number, greater is the need to take sun safety precautions. To learn more visit ec.gc.ca/UV.

Canada's Wind Chill Index
Helping you Deal with the Cold You Feel
The cooling sensation caused by the combined effect of temperature and wind is called wind chill. The wind chill index is not actually a real temperature but, rather, represent the feeling of cold on your skin and is expressed in temperature-like units. Exposed skin at very cold wind chills can freeze in only minutes. The best way to avoid the hazards of wind chill is to check the weather forecast before going outside and to be prepared by dressing warmly. The risk of frostbite increases rapidly when wind chill values go below -27.
Seven Steps to Cold Weather Safety
- Check the weather forecast before planning outdoor activities.
- Dress in layers with a wind resistant ourer layer, wear a hat, mittens, scarf or face mask, and insulated, waterproof footwear. When it is very cold, or when the wind chill is significant, cover as much exposed skin as possible. Your body's extremities, such as the ears, nose, fingers and toes, lose heat the fastest.
- Limit your time outdoors when it is very cold or when the wind chill is significant.
- Seek shelter - get out of the wind
- Stay dry - wet clothing chills the body rapidly.
- Keep active to stay warmer - walking or running will help warm you by generating body heat.
- Watch for signs of frostbite - numbess and white patches on skin. Some people are more susceptible to the cold - particularly children, the elderly and those with circulation problems.
|Wind Speed (km/h)||0||-5||-10||-15||-20||-25||-30||-35||-40||-45||-50|
- 0 to -9, Low risk of frostbite
- -10 to -27, Moderate Risk
- -28 to -39, High risk in 30 minutes of exposure
- -40 to -47, Very high risk in 5 to 10 minutes of exposure
- -48 to -54, Severe risk in 2 to 5 minutes of exposure
- -55 and colder, Extreme risk in 2 minutes or less exposure
