Average Amount of Cloud a Year at Canada's Cities

Pulled together here is information on how cloudy Canadian cities normally are during the year.

The tables below give typical annual totals for the hours of cloudy skies at major cities across the country. The hours only count heavy overcast, when cloud covers anywhere from 80 to 100 percent of the sky.

There are also data on the usual number of days a year that lack sun. These are days with no measurable bright sunshine.

All the numbers are averages of weather statistics collected from 1981 to 2010.
