Summer 2011 UV Outlook



26 May 2011
Press Release Number:

Environment Canada scientists predict that UV (ultraviolet) values across Canada will be about three to four per cent higher during the summer months, and possibly even higher for some days in the spring, as compared to pre-1980 levels, due to the reduced thickness of the ozone layer. Record ozone thinning in the Arctic this spring is expected to contribute to these higher UV values.
