Weather in Washington in May
May is when Seattle stops apologizing for itself. Highs push into the low to mid 60s, lows hover around 48-50°F, and rainfall drops to about 2 inches. That's drier than most of the country. Locals start acting like they live in California, and honestly, the weather backs them up.
The big shift: daylight. You're getting 15+ hours of it by late May. Sunset doesn't happen until nearly 9pm, which means you can cram a full day of sightseeing and still catch golden hour from Kerry Park. The Cascades still have snow above 5,000 feet, but lower elevation trails are clearing fast.
Eastern Washington — Walla Walla, Ellensburg — runs 5-10 degrees warmer than Seattle. The San Juan Islands are a touch cooler with more wind, but sunny days there hit different when you're watching orcas from a kayak.
- •May averages 55-60% chance of sunshine on any given day. That's genuinely good for Seattle. Plan outdoor activities and have one indoor backup day.
- •Memorial Day weekend (late May) marks the unofficial start of summer tourism. Book accommodation before that weekend or pay a premium.
What to Pack
Layers. Always layers in the Pacific Northwest, even in May. A lightweight rain shell for the occasional shower, sunglasses you'll actually use now, and comfortable walking shoes. If you're hitting Rainier trails, bring proper hiking boots and a warm mid-layer — it's still winter up there. Sunscreen is non-negotiable; that high-latitude UV sneaks up on you.
Mount Rainier: The Big Reveal
May is when Rainier transitions from "that mountain you see from Seattle" to "the place you actually go." The road to Paradise — the park's most popular area at 5,400 feet — typically opens by mid-May, though exact dates depend on snowpack. Sunrise (the area, not the time of day) usually stays closed until late June or July.
Here's the thing about Rainier in May: you're catching it in the in-between. Snow is still deep at Paradise — often 8-12 feet — but it's melting. The first wildflowers won't carpet the meadows until July, but you'll see avalanche lilies pushing through snow edges and glacier lilies in lower clearings. It's raw and dramatic in a way that the postcard-perfect summer version isn't.
- •Check the NPS road status page before driving. Paradise Road can close temporarily for late-season storms even in May.
- •Gas up in Ashford. There's nothing inside the park.
- •The mountain makes its own weather. Clear skies in Seattle mean nothing for Rainier. Check the Paradise webcam before committing to the drive.

What's Open and What's Not
Paradise: Usually accessible by mid-May. The Henry M. Jackson Visitor Center opens weekends first, then daily. The parking lot fills by 10am on sunny weekends — arrive early or go midweek. Trails above Paradise are snowshoe or crampon territory.
Longmire: Open year-round at 2,760 feet. The historic inn, museum, and lower trails are snow-free by May. The Trail of the Shadows (0.7 miles, flat) and Carter Falls trail are good early-season options.
Sunrise: Closed. Don't even think about it until late June at earliest. The road at 6,400 feet is buried.
Snow Activities at Paradise
May snow at Paradise is perfect for snowshoeing. Ranger-led snowshoe walks run on weekends when the visitor center is open — free with park entry. Bring your own snowshoes or rent in Ashford ($15-25/day). The views of Nisqually Glacier from the snow-covered Skyline Trail are staggering.
Some visitors bring sleds. The designated snow play area near the upper parking lot works until the snow gets too slushy in the afternoon.
The Drive Itself
The approach from Seattle takes about 2.5 hours via Ashford on the southwest side. The drive through the Nisqually entrance climbs through old-growth forest — Douglas fir and western red cedar trees that were growing before Columbus. Stop at Narada Falls (a short walk from the road) on the way up.
San Juan Islands: Peak Whale Watching
May is prime time in the San Juans. Orca sighting rates climb to 90%+ as the Southern Resident killer whales follow chinook salmon runs through Haro Strait. The weather cooperates more than April, and summer crowds haven't arrived yet. This is the sweet spot.
The islands themselves are stunning in May. Wildflowers blanket the prairies on San Juan and Lopez Islands. Madrone trees glow red against the blue water. Bald eagles are nesting and easy to spot. It feels like the Pacific Northwest's best-kept secret, except it isn't a secret at all.
- •Book whale watching tours at least a week ahead for May weekends. Weekday slots are easier to grab.
- •Vehicle ferry reservations from Anacortes fill up fast in May. Book 2-3 weeks out or go as a walk-on passenger.
- •Bring binoculars. Even if you book a boat tour, you'll want them for land-based wildlife spotting too.
| Category | Price Range |
|---|---|
| Whale watching boat tour | $110-160/person |
| Kayak whale watch tour | $95-130/person |
| Ferry walk-on (Anacortes) | $14.45 each way |
| Ferry vehicle | $55-70 each way |
| Bike rental (Lopez) | $40-60/day |
| Discover Pass | $10/day or $30/year |
Whale Watching Options
Half-day boat tours (3-5 hours) depart from Friday Harbor on San Juan Island multiple times daily. Companies like San Juan Safaris, Western Prince, and Maya's Legacy run boats ranging from 28-passenger cruisers to smaller zodiacs. Zodiac tours get you closer to the water (and wetter) but are more thrilling.
Kayak tours combine whale watching with paddling — a 3-hour guided tour puts you at water level with potential orca sightings. Not guaranteed on kayak trips, but when it happens, it's a story you'll tell for years. Companies like Outdoor Odysseys and Crystal Seas run May tours daily.
Land-Based Whale Watching
Lime Kiln Point State Park remains the best shore-based whale watching spot on the planet. The lighthouse sits on a rocky point where orcas pass within 100-300 yards. May afternoons are your best bet — bring binoculars, a camp chair, and patience. It's free with a Discover Pass ($10/day or $30/year).
Beyond Whales
Lopez Island is the flattest San Juan — perfect for cycling. Rent bikes in the village and loop the 32-mile island road. Orcas Island (no relation to the whales) has Mount Constitution, the highest point in the islands at 2,409 feet, with 360-degree views from a stone observation tower. San Juan Island Lavender Farm starts blooming in late May.
Seattle: Outdoor Season Begins
May Seattle is the city at its most confident. Outdoor patios are packed. Runners crowd the Burke-Gilman Trail. The Olympic Mountains appear across the Sound like they've been photoshopped in. Everyone is unreasonably happy, and frankly, they've earned it after seven months of gray.
| Category | Price Range |
|---|---|
| Coffee at specialty roaster | $5-7 |
| Pike Place flower bouquet | $8-15 |
| Dinner for two (mid-range) | $80-130 |
| Chihuly Garden and Glass | $32 |
| Space Needle | $35-40 |
| Museum of Pop Culture | $35 |
Food and Coffee
Seattle's food scene in May is driven by spring produce: morel mushrooms, fiddlehead ferns, spring king salmon (the first of the season), and spot prawns. Restaurants compete to get these ingredients on menus first.
Must-hit spots: Canlis (splurge, $200+/person, but the view of Lake Union is absurd), The Walrus and the Carpenter in Ballard (oysters, spot prawns), and Stateside on Capitol Hill (Vietnamese with a Seattle spin). For casual excellence, Un Bien in Ballard does a Caribbean-roasted pork sandwich that has no business being as good as it is.
Coffee: This is Seattle. You're not going to Starbucks. Elm Coffee Roasters in Pioneer Square, Victrola on Capitol Hill, and Slate Coffee Roasters in Ballard are the locals' picks. Espresso quality here is legitimately world-class.
Neighborhoods Worth Your Time
Ballard: Sunday farmers market (the best in the city), brewery row along Leary Way, the Locks where boats move between Lake Union and Puget Sound. Evening: cocktails at Hazlewood or beer at Stoup Brewing.
Capitol Hill: Seattle's cultural nerve center. Pine/Pike corridor for bars and restaurants. Volunteer Park for views and the conservatory. Cal Anderson Park for people-watching.
Fremont: Self-declared "Center of the Universe" with public art (the Troll under the bridge, the Lenin statue), vintage shops, and the Sunday market. Eccentric and proud of it.
Georgetown: Industrial grit turned creative. Distilleries (Westland Whiskey, Copperworks), the Georgetown Trailer Park Mall, and some of the best dive bars in the city.
Pike Place Market in May
The market is alive in a way that winter can't match. Flower vendors have peonies, ranunculus, and irises. The produce stalls stock spring asparagus, rhubarb, and early strawberries. Arrive before 9am on weekdays to see the fishmongers set up and throw salmon around without tourist gridlock.
Pro move: skip the main arcade level and head downstairs to the lower levels. PostAlley for gum wall photos (it's gross but you'll do it anyway), and the small shops and vintage posters that most visitors walk right past.
Olympic Peninsula: Rainforests and Beaches
The Olympic Peninsula is Washington's wild card. Temperate rainforest, rugged Pacific beaches, and snow-capped mountains — all within a three-hour drive of Seattle. May is when it starts to make logistical sense: roads are open, rain is tapering, and the trails are clear enough to actually enjoy.
- •The Hoh Rainforest parking lot fills by 10am on May weekends. Arrive before 9am or visit midweek.
- •Combine Olympic Peninsula with the San Juan Islands for a full Washington nature loop. Seattle → Olympic Peninsula → Anacortes → San Juans → Seattle.
- •Cell service is spotty to nonexistent on much of the peninsula. Download offline maps before leaving Port Angeles.
| Category | Price Range |
|---|---|
| Olympic National Park entry | $30/vehicle |
| Bainbridge ferry (walk-on) | $9.45 each way |
| Port Angeles lodging | $100-200/night |
| Forks lodging | $80-160/night |
Hoh Rainforest
This is what a temperate rainforest looks like: every surface draped in moss, ferns covering the forest floor, Sitka spruce trees so big you can't wrap your arms around them. The Hall of Mosses trail (0.8 miles) is the greatest hits version — short, flat, and jaw-dropping.
The Spruce Nature Trail (1.2 miles) follows the Hoh River and is less crowded. May rainfall in the Hoh averages about 8 inches — significantly less than winter's 15+ inches — but bring rain gear. This is a literal rainforest.
Pacific Beaches
Rialto Beach and Ruby Beach are the stars. Sea stacks, driftwood the size of school buses, and tidepools full of sea stars and anemones. May brings the lowest tides of the year in the late afternoon — perfect for tidepool exploration. Check tide charts before going.
These are not swimming beaches. Water temperature is 48-52°F. They're for walking, exploring, and feeling small next to the Pacific Ocean.
Hurricane Ridge
The road to Hurricane Ridge (5,242 feet) in Olympic National Park typically opens daily by mid-May. On clear days, you can see Vancouver Island, the San Juan Islands, and Mount Baker from the summit. The Klahhane Ridge trail has early wildflowers by late May. Snow lingers on north-facing slopes.
Getting There
From Seattle, take the Bainbridge Island ferry (35 minutes, $9.45 walk-on) and drive west. Port Angeles is the main gateway town — about 2.5 hours from the ferry terminal. Budget two full days minimum: one for the rainforest and beaches, one for Hurricane Ridge and Port Angeles.
Late Tulips and Spring Blooms
The Skagit Valley Tulip Festival officially ends April 30, but here's the insider move: some tulip fields still have late-blooming varieties into the first week of May. You won't get the full festival experience, but the fields are less crowded and the flowers are often still vibrant. Call Tulip Town or RoozenGaarde before driving up.
Beyond tulips, May is prime rhododendron and azalea season across western Washington. The Rhododendron Species Botanical Garden in Federal Way (30 minutes south of Seattle, $8 entry) has one of the world's largest collections. Kubota Garden in south Seattle is free and features Japanese maples alongside spring blooms.
The Washington Park Arboretum in Seattle peaks in May. Azalea Way is a quarter-mile promenade lined with blooming azaleas and dogwoods — it's the most photogenic walk in the city and it's free.

| Rhododendron Garden entry | $8 |

Where to Stay
May is the last month of shoulder-season pricing before summer rates kick in after Memorial Day. Book the first three weeks of May for the best value. The last week starts creeping up.
| Category | Price Range |
|---|---|
| Downtown Seattle | $160-280/night |
| Capitol Hill | $130-200/night |
| San Juan Island | $160-320/night |
| Olympic Peninsula | $100-220/night |
| Ashford (Rainier gateway) | $120-220/night |
Downtown Seattle ($160-280/night)
Best for first-timers and short stays. Walk to Pike Place, the waterfront, and Pioneer Square. The Thompson Seattle on 1st Avenue has rooftop views of Elliott Bay. Hotel Andra in Belltown is a solid boutique pick. Rates jump 15-20% for Memorial Day weekend.
Capitol Hill ($130-200/night)
The move if you care about food and nightlife. Light rail to downtown in 5 minutes. More local energy, fewer tourists. The 11th Avenue Inn and Gaslight Inn are neighborhood gems. You'll walk up hills. That's the deal.
San Juan Island ($160-320/night)
Friday Harbor has the most options: inns, B&Bs, and a few boutique hotels. Roche Harbor Resort on the north end is the splurge pick with a marina and sculpture park. Lakedale Resort has glamping options starting at $200/night. Book 3-4 weeks ahead for May weekends.
Olympic Peninsula ($100-220/night)
Port Angeles is the gateway with the most lodging. Lake Crescent Lodge is the romantic option — a historic lodge on a glacial lake inside Olympic National Park. Kalaloch Lodge on the coast has bluff-top cabins overlooking the Pacific. Both book up fast in May.
