The amount of wind that Canada's major cities average in a year is listed below. The tables give the normal annual wind speed, in miles per hour (mph) and kilometres per hour (kph). There's also information on how many days a year have strong winds, when it blows at least 52 kph (32.3 mph).
The Homogenized Surface Wind Speed data consist of monthly, seasonal and annual means of hourly wind speed (kilometres per hour) at standard 10 metre level for 156 locations in Canada.
historical climate data web site is a gateway to information on matters such as past (hourly, daily, monthly and almanac) weather includes: temperature, snow, snow on ground, precipitation, rain, wind speed and direction, heating and cooling degree days, visibility, relative humidity, wind chill and humidex in Canada.

Long-term homogenized surface wind speeds (at standard 10 m level) have been specifically developed for climate research in Canada. The data consist of hourly and monthly mean surface wind speeds for more than 100 locations. Series start from 1953 or later and all stations have at least 45 years of continuous observations.
The original data includes hourly surface wind speeds extracted from the National Climate Data Archive of Environment Canada. There are no joined stations.
Surface wind speeds were homogenized in two steps. First, metadata and a logarithmic wind profile were used to adjust hourly wind speeds measured from non-standard to the standard 10 m height. Then, the monthly mean wind speeds were tested for homogeneity using a technique based on regression models (Wang, 2008). Homogeneous monthly mean geostrophic wind speeds, derived from homogenized sea level pressure, were used as reference series.
The homogenization methodology involves the identification of shifts in the wind speed time series due to changes in anemometer height, site exposure, location, instrumentation and anemometer type. Monthly adjustments were derived from the regression models (Wan et al., 2009). Hourly data were adjusted from non-standard to the standard 10 m height. Whenever possible, the main causes of the identified inhomogeneities were retrieved through historical evidence such as the inspection reports.
