NOAA publishes no 1991-2020 snowfall normal for this station. The nearest record that keeps one, Portland (3 miles away), gets 4 inches of snow in a normal year; elevation and distance can change that.

When is the best weather to visit Vancouver?

Normal highs sit between 65°F and 85°F in May, June, July, August and September. Of those, August has the fewest days with rain (4).

That is a measurement, not a recommendation: it counts the months whose normal afternoon high sits between 65°F and 85°F, where a light layer is enough by day.

When is the last frost in Vancouver?

In Vancouver, the last spring frost (32°F) comes after March 29 in half of years and after April 18 in one year in ten; the first autumn frost comes before November 9 in half of years and before October 22 in one year in ten.

First autumn frost, half of years before
November 91 year in 10 before October 22; 9 in 10 before November 30

NOAA puts the median frost-free season at 223 days, and the season without a hard freeze (28°F) at 264 days.

A hard freeze (28°F) comes after March 3 in half of springs and before November 26 in half of autumns.

The USDA's 2023 Plant Hardiness Zone Map puts Vancouver in zone 8b across its 9 ZIP code areas (8b in 98660, the largest). By the map's own method, the average of each year's coldest night over 1991-2020, Vancouver's NOAA station is in zone 8b: the coldest night of a typical year reaches 18°F (24 complete years).

How much heating and cooling does Vancouver need?

A normal year in Vancouver brings 4,400 heating degree days, 18% fewer than the median U.S. place (5,373), and 400 cooling degree days, 56% fewer than the median (908). Seven months need 300 or more heating degree days, a monthly mean of about 55°F or colder. For gardens and crops, NOAA counts 2,573 growing degree days a year above 50°F.

How does Vancouver's climate compare?

Vancouver is warmer than 93 of the other 95 places with their own NOAA record in Washington, and wetter than 56. Across the 7,247 U.S. stations with normals, its annual mean of 54.0°F is warmer than 57%.

In the Köppen classification computed from these normals, Vancouver is Csb: temperate, dry-summer, warm summer. What the classes mean.

Which places near Vancouver share this climate record?

16 places have no NOAA station with 1991-2020 normals of their own, and this station is the nearest full record. A place's own climate can differ from these figures, by several degrees where it sits much higher or lower than the station, nearer the coast, or inside a large city's heat; for the larger places the next nearest records are named with their yearly mean, so the spread around them is visible, and places of 50,000 or more have their own page with NOAA's gridded normals.

Does it snow in Vancouver?

Yes. NOAA publishes no 1991-2020 snowfall normal for Vancouver's NOAA station; the nearest record that keeps one, Portland (3 miles away), records 4 inches of snow in a normal year.

What is the rainiest month in Vancouver?

December, with 6.07 in of precipitation in a normal year; the driest is July with 0.42 in.
