Vancouver weather by month — averages, rainfall & climate trends

Wrapped between the Pacific and the Coast Mountains, Vancouver enjoys one of Canada's mildest climates — soft, rainy winters and clear, dry summers that have made its grey skies and green surroundings part of the city's identity. Average temperatures and rainfall by month, a climate graph, today's conditions versus the long-term average, and how the climate has shifted since 1940 — all on one page for Vancouver, Canada.

Area we sample

Each city's history comes from one ERA5 grid cell — about 28 km across, shown by the dashed box. Near mountains or coasts, conditions can vary across the cell.

Location & data

Historical weather for Vancouver is sampled from the ECMWF ERA5 reanalysis at 49.25°N, 123.12°W, with daily records since 1940.

Last 30 days

15 of the last 31 days were warmer than the historical average for that date. Average difference: +0.6°C.

Each bar is one day, from morning low to afternoon high. Warm-colored bars are days whose mean ran above average; cool bars ran below. The dot inside the bar is the daily mean. The shaded band is the typical 10–90% range expected for that date. Average = the day's mean temperature averaged across every year of record (1940–2026) for that calendar date.

This date over the years

One dot per year — the mean temperature on this calendar date. Dots are warmer or cooler than the long-term average (dashed line); the shaded band is the typical 10–90% range, and the highlighted dot is today's forecast. Based on ERA5 reanalysis — modelled estimates, not station readings.

Climate overview

Vancouver has an oceanic climate (Köppen Cfb) that borders on a warm-summer Mediterranean type, and is among the mildest and most temperate in Canada. The Pacific Ocean is the dominant influence, with Vancouver Island sheltering the city from the open ocean across the Strait of Georgia. Winters are mild and wet — most days from November through March see some rain — while summers are notably drier, with precipitation on only about one day in five through July and August.

Rain, far more than snow or heat, defines Vancouver's reputation. Snow falls on only a handful of days each year and rarely lingers on the ground, and the surrounding ocean and mountains keep temperature extremes uncommon. The wet, grey winters and bright, dry summers give the city its characteristic maritime rhythm.

The year peaks in August, at 17.9°C over the day and around 23.1°C by mid-afternoon. The coolest month is January, when daily means fall to about 2.9°C and overnight lows sit around 1.1°C.

In total, Vancouver averages about 2416 mm of precipitation a year; November is usually the wettest month (342 mm) and July the driest (63 mm). A typical year brings rain or snow on around 180 days.

The record here starts in 1940, and since then the annual mean in Vancouver has climbed 1.6°C from the first ten years to the last ten. Where the first decade averaged 50 frost days a year, the recent one saw about 25.

Climate graph (climograph)

August is the warmest month, January the coolest — a yearly swing of 15°C. Wettest month: November (~342 mm). Whole year averages ~2416 mm of rain.

Bars = average monthly rainfall (right axis). Lines = average daily high and low (left axis). Average = each month's value averaged across every year of record (1940–2026).

Vancouver month by month — what to expect

Typical conditions for each month, averaged across the full record (since 1940). Daylight is the time from sunrise to sunset. Record high/low are the most extreme values in the ERA5 dataset (modelled since 1940), so they can differ from official weather-station readings.

How it has changed

Year-by-year signals from 1940 to today.

Climate stripes

Annual mean shifted from 1940–1949 to 2016–2025 by +1.6°C.

Each vertical stripe is one year. Color encodes how much that year's annual mean differed from the long-term average. Average = each year's annual mean compared to the average of all years (1940–2026). cooler ← → warmer

Annual mean temperature

Long-term trend: +0.24°C per decade.

One point per year — the temperature averaged across the whole year. The dashed line is the least-squares long-term trend. Based on ERA5 reanalysis — modelled estimates, not station readings.

Seasonal warming

Dec–Feb is warming fastest: +0.32°C per decade.

Each faint line is one three-month period's average per year; the bold dashed line is its long-term trend. Different parts of the year often warm at different rates. Based on ERA5 reanalysis — modelled estimates, not station readings.

Hot days vs frost days

Days ≥ 30°C per year: 3.0 early in the record → 4.1 recently. Frost days: 50 → 23.

Thin lines are raw yearly counts; thick lines are the smoothed trend that removes year-to-year noise. The hot-day threshold is auto-picked per city so the line actually moves. Average = a centered 5-year rolling average to smooth weather noise.

Yearly hot & cold extremes

All-time high in 2021, all-time low in 1950: 38.3°C / -18.9°C.

One point per year — the single hottest and coldest day recorded that year.

Annual rainfall

~2416 mm/year on average. Last decade ran −3% vs that average. Long-term trend: 18 mm per decade.

One bar per year of total rainfall. Dashed line is the long-term average. Average = the average annual rainfall across every year of record (1940–2026).

Day-by-day grid

Each tiny square is one calendar day across the full record — ~30,000 days per city. Use the mode switch above the chart: Anomaly colors each day by how far it ran from the historical average for that date (red = warmer, blue = cooler), Daily mean temp shows the absolute mean temperature for the day (useful to see seasons and heatwaves), and Precipitation shows daily rainfall (useful to spot wet/dry seasons and droughts). Average = the long-term average for that calendar date (1940–2026).
