May in Vancouver, Washington stays true to the Pacific Northwest pattern with temperatures from 47°F to 64°F and about 11 rainy days, as the Columbia River valley keeps the city cooler and wetter than the Willamette Valley to the south. A quality waterproof jacket over light layers is the practical uniform for exploring the Fort Vancouver National Historic Site and the Columbia River waterfront trail. The city's proximity to the Columbia River Gorge makes breathable but wind-resistant layering especially important.

Based on typical May conditions in Vancouver. Weather varies year to year — check the live forecast when you're within two weeks of your trip.
May in Vancouver, Washington shares the Pacific Northwest's signature spring character with its neighbor Portland just across the Columbia River — rain is frequent, temperatures are mild but never truly warm, and the lush green landscape justifies every wet day. Fort Vancouver National Historic Site's grounds are beautiful in May when the orchards planted by the Hudson's Bay Company are in bloom, and the Columbia River Renaissance Trail offers scenic river views on the relatively rare but genuinely beautiful clear days. The Columbia River Gorge to the east creates its own microclimate influence, with wind a near-constant factor in the lower Gorge area that affects Vancouver more than cities further from the river. This wind chill makes a windproof outer layer more important than just a rain jacket — the combination of 60°F air and a Gorge wind gust is substantially colder than the temperature alone suggests. Dress in functional Pacific Northwest layers: a quality wind-resistant rain jacket, light to medium sweater, and waterproof footwear handle May's full range of conditions.
A black rain jacket over an oversized graphic tee and olive cargo trousers handles mild rain practically. White lace-up booties finish the look with enough contrast to lift the palette.
A grey longline coat over an ivory blouse and black wide-leg trousers handles mild rain without losing formal intent. Black Chelsea boots and a mini bag keep it focused.
A black longline parka over a cable knit sweater in mild rain keeps warmth without overdressing. Black mule heels under leggings are an unexpected and intentional detail.
A navy trench coat over khaki bermuda shorts and a blue linen blouse works between seasons on a mild rainy day. Black pointed-toe heels sharpen what could easily be too casual.
A cream oversized puffer over a navy striped cardigan and wide-leg ivory linen trousers handles mild rain with a considered mix of textures. Black ballet flats are the restrained finish.
An olive anorak handles mild rain without abandoning the polish of wide-leg navy trousers underneath. The crossbody stays tucked and close.
A blush cropped jacket over a grey cardigan and black sweater mini skirt handles mild rain with charm. A black bucket bag and ankle boots keep the proportions balanced.
Layer in Pacific Northwest fashion for Vancouver's cool, often-rainy May: a light sweater or long-sleeve top under a windproof waterproof jacket, with dark jeans or slim trousers and waterproof ankle boots or leather sneakers. Mornings in the upper 40s require a genuine warm layer. The Columbia River wind makes a windproof outer layer more important than simply a rain jacket.
May is a pleasant time to visit Vancouver — Fort Vancouver National Historic Site is beautiful with spring blooms, the Columbia River waterfront is scenic, and the proximity to Portland means excellent dining and cultural access just across the bridge. The weather is typical Pacific Northwest spring: cool, occasionally rainy, but manageable and often punctuated by lovely sunny afternoons. Dress accordingly and you'll enjoy the visit.
Waterproof ankle boots or waterproof leather sneakers are ideal — rain-slicked sidewalks and the Columbia River trail's compacted gravel surface both benefit from footwear that handles moisture. Avoid suede or unprotected leather. For Fort Vancouver's historic grounds, comfortable walking shoes with good traction handle both paved paths and softer grass areas in wet weather.
Vancouver in May averages lows near 47°F and highs around 64°F, with about 11 rainy days typical of the Pacific Northwest spring. The Columbia River corridor adds a wind element that makes outdoor time feel cooler than the temperature suggests. Sunny days can briefly warm to the upper 60s, but rain and cloud cover are the default setting through much of the month.
A quality windproof and waterproof jacket is the essential item for a Vancouver May visit. Pack medium-weight sweaters, dark jeans or trousers, waterproof ankle boots or leather sneakers, and a compact umbrella as backup. A merino base layer adds warmth without bulk on the coldest days. Leave sandals and summer dresses for June and July — May in the Pacific Northwest rewards proper rain-ready layering.
