Precipitation

A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Vancouver varies significantly throughout the year.

The wetter season lasts 6.4 months, from October 9 to April 22, with a greater than 36% chance of a given day being a wet day. The chance of a wet day peaks at 60% on November 18.

The drier season lasts 5.6 months, from April 22 to October 9. The smallest chance of a wet day is 11% on August 5.

Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 59% on November 18.

The solar day over the course of the year 2017. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.

Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The perceived humidity level in Vancouver, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Vancouver experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 5.7 months, from October 18 to April 10, with average wind speeds of more than 2.5 miles per hour. The windiest day of the year is December 4, with an average hourly wind speed of 3.6 miles per hour.

The calmer time of year lasts for 6.3 months, from April 10 to October 18. The calmest day of the year is August 9, with an average hourly wind speed of 1.6 miles per hour.

Solar Energy

This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.

The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.3 months, from May 12 to August 21, with an average daily incident shortwave energy per square meter above 5.5 kWh. The brightest day of the year is July 20, with an average of 6.7 kWh.

Data Sources

This report illustrates the typical weather in Vancouver, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Vancouver.

For each station, the records are corrected for the elevation difference between that station and Vancouver according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

The estimated value at Vancouver is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Vancouver and a given station.

The stations contributing to this reconstruction are: Vancouver Harbour (60%, 3.7 kilometers, north); Vancouver International Airport (31%, 8 kilometers, southwest); P. Meadows Coastal Station Automatic Weather Reporting System (4.5%, 32 kilometers, east); and White Rock Automatic Weather Reporting System (3.8%, 36 kilometers, southeast).

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
