Weather in Vancouver in May
Canada · 20-year averages, May
Shoulder season. May sits in between. You will get good days and you will lose some. You should expect rain on 15 days of the month, which is more days wet than dry.
May ranks 5 of 12 in Vancouver: past the worst of the year but short of July, which is the month to book if the dates are open.
Rain on 15 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 17.1 °C days and 9.6 °C nights; the spread matters more here than any single number.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest May day reached 31.2 °C and the coldest night fell to 2.4 °C, and the wettest single day dropped 32 mm — roughly 33% of the month's rain in one day.
May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 142 mm against 22 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 96 mm average is a reasonable planning figure, not a promise.
Wind is light at 2.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.
How May sits in the year
The month is on the way up: 6 °C warmer than April, and June adds another 2.9 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.
Daylight in May
15.3 hours of daylight, gaining 1.3 hours across the month. That is between Vancouver's extremes of 16.2 and 8.2 hours, so days are long enough not to constrain the plan.
An inland climate
Despite being inland, the year stays fairly even: 23.6 °C between the year's warmest afternoons and coldest nights.
How busy it gets
Busy. Popular without being frantic; book the things you care about, improvise the rest.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
May in Vancouver versus nearby
If Vancouver is one option among several, the nearby comparison is worth making. Maple Ridge is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Nanaimo is a better bet in May — within a degree on temperature, 4 days less rain.
So: May is a compromise. July is 21 points better and is what Vancouver is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
