Over the last decade (2015–2024), Vancouver’s annual rainfall has fluctuated significantly, reflecting both wetter and drier years within the city’s temperate maritime climate. Reliable records from Extreme Weather Watch and Environment Canada show the following approximate totals.
Vancouver annual rainfall (2015–2024)
Year | Precipitation (mm) | Comment |
2024 | 567 mm | Exceptionally dry year, well below normal [1] |
2023 | 1159 mm | Typical wet year [1] |
2022 | 1352 mm | Above-average rainfall [1] |
2021 | 1521 mm | Very wet, included atmospheric river events [1] |
2020 | 992 mm | Slightly below normal [1] |
2019 | 1130 mm | Moderate year [1] |
2018 | 1721 mm | Wettest year of the decade [1] |
2017 | 1546 mm | Above normal [1] |
2016 | 1618 mm | Significantly wetter than average [1] |
2015 | 1441 mm | Slightly above normal [1] |
(Note: 1 cm = 10 mm precipitation conversion)
Decadal overview
- Average (2015–2024): approximately 1,305 mm/year.
- Wettest year: 2018 (1721 mm).
- Driest year: 2024 (567 mm).
- Vancouver’s 30-year climate normal from 1991–2020 is about 1,189 mm annually, meaning most years in this decade were wetter than the long-term average except for 2020 and 2024.[2]
Interpretation
Most of the rainfall occurs from October to March, consistent with the city’s oceanic climate regime. The sharp drop in 2024 rainfall corresponds with Western Canada’s regional drought cycle, while 2021’s wet conditions align with record-breaking atmospheric rivers that caused flooding across British Columbia.[1][2]
In summary, Vancouver’s past decade shows high precipitation variability around a stable long-term mean, driven largely by Pacific weather patterns and El Niño/La Niña influences.
