Bellingham & Lummi

Getting There

Bellingham sits at the northern end of Washington’s inland waters, about 90 nautical miles north of Seattle and just 25 miles south of the Canadian border. Most cruisers reach Bellingham Bay via Rosario Strait from the south, passing through the San Juan Islands or running up the east side of Whidbey Island. From the north, boats clear US Customs at Blaine or Roche Harbor before continuing south into Bellingham Bay.

Squalicum Harbor is the primary destination — a large, well-run public marina with transient moorage, fuel, and walking-distance provisioning in downtown Bellingham. Charter companies based here outfit boats for the San Juans, Gulf Islands, and longer passages north to Desolation Sound and the Inside Passage.

For boats heading to Canada, Blaine Harbor and Semiahmoo Marina are the staging points. US Customs has a facility at Blaine, and Canadian Border Services (CBSA) can be cleared by phone via CANPASS or at designated ports of entry like Bedwell Harbour on South Pender Island.

When to Go

Peak season is July through August, when Bellingham Bay is at its warmest and the charter fleets are fully deployed. Squalicum Harbor guest moorage fills on summer weekends, though mid-week availability is usually fine. This is also prime time for heading north — most cruisers staging for the Inside Passage depart between late June and mid-July.

Shoulder season (May-June, September) is excellent for local cruising. Bellingham’s maritime climate keeps things mild, and the reduced traffic means easier moorage everywhere. September is particularly pleasant — warm days, calm seas, and the fall light on the San Juan Islands is extraordinary.

Spring and fall see increasing numbers of boats heading north or returning south, making Bellingham a natural layover. Winter cruising is possible but demands respect — the area is exposed to southeast gales, and marina services scale back.

Currents & Tide Planning

Bellingham Bay itself has modest currents, but the surrounding passages can run hard. Hale Passage between Lummi Island and the mainland sees currents up to 3 knots, and Bellingham Channel between Lummi and the San Juans carries significant tidal flow.

For boats heading north to the border, the waters between Blaine and Point Roberts are relatively straightforward, but Boundary Pass — the international boundary line between the US and Canadian islands — can produce steep chop when wind opposes current.

Rosario Strait, the eastern approach from the south, runs 2-3 knots and builds uncomfortable seas when strong southerlies meet an ebb tide. Time your transit or take the inside route through Swinomish Channel as an alternative (timing Deception Pass carefully).

BoatRoutes shows current conditions for every route in and out of Bellingham Bay, so you can plan transits that work with the tidal flow.

What Makes It Special

Bellingham occupies a unique position in Pacific Northwest cruising. It is simultaneously a vibrant college town with excellent restaurants and provisioning, a major charter base for the San Juans, and the last US harbor before Canadian waters. That triple role gives it an energy most ports this size do not have.

The setting is hard to beat. Mount Baker looms to the east — a volcanic cone that catches alpenglow in the evening and provides an unmistakable landmark from anywhere on the water. The Chuckanut shoreline to the south features sandstone cliffs, old-growth forest, and some of the most beautiful coastal scenery in Washington.

For cruisers, Bellingham works as both a destination and a launching point. Spend a night at Squalicum, provision at the downtown co-op or farmers market, and then choose your direction: south to the San Juans, west to Lummi and the outer islands, or north across the border to the Gulf Islands and beyond. Few harbors offer that many options within a day’s cruising range.
