Climate

The BC Coast is dominated by a moderate oceanic climate (Köppen: Cfb) with warm summers, cool winters, and constant rainfall that peaks during the winter months. These areas enjoy the mildest winter weather in all of Canada, as temperatures rarely fall below freezing.

The southernmost region of the coast (surrounding the Salish Sea) features a warm-summer Mediterranean climate with warm, dry summers and cool, wet winters. This gradually transitions to a predominantly oceanic climate in the north along the coast and further inland into the foothills of the Pacific Ranges. Higher elevations feature a subpolar oceanic climate (Köppen: Cfc) with cool summers, cold winters, and constant rainfall that peaks during the winter months. The highest elevations feature a subarctic climate (Köppen: Dfc).

Ecology

The British Columbia Coast is dominated by temperate rainforest. According to the ecoregion system used by the World Wide Fund for Nature (WWF), the BC Coast is part of five distinct ecoregions: Puget lowland forests, Central Pacific coastal forests, British Columbia mainland coastal forests, Haida Gwaii coastal forests, and Pacific Coastal Mountain icefields and tundra.

According to the ecozone system used by Environment and Climate Change Canada (ECCC), the BC Coast is part of four distinct ecozones: Pacific Coastal Mountains, Coastal Western Hemlock-Sitka Spruce Forests, Pacific and Nass Ranges, and Strait of Georgia/Puget Lowland.

According to the British Columbia Ministry of Forests, which uses an ecosystem classification system independent of the WWF and ECCC, the BC Coast is part of two distinct biogeoclimatic zones: Coastal Western Hemlock and Coastal Douglas-fir.

Regional districts

Below are the 15 regional districts of British Columbia defined as being in the Coast region:

Fishing

Trawling for herring in the Salish Sea

The fishery of the Pacific Northwest Coast is legendary, especially for its many salmon runs and the cultures that built on top of them throughout the region. Salmon runs have greatly diminished since pre-Contact years and the advent of commercial canning and, ultimately, depletion of stocks by high-seas fishing.

Other commercial fisheries include halibut, herring and herring roe, sea urchin and other specialty sushis, hake, haddock, cod, crab and shellfish.

Highways

The Coast Region of B.C is connected to the rest of B.C by various roads depending on the region.

The populous Fraser Valley and Lower Mainland is linked to the rest of the province by Highway 1 (Fraser Canyon Highway), Highway 5 (Coquihalla Freeway), Highway 3 (Crowsnest Highway) and Highway 99 (Sea to Sky Highway). The Lower Mainland is also connected to the U.S. by four highway border crossings with the Peace Arch on Interstate 5 being the largest. Several freeways connect lower mainland communities together.

The backbone of Vancouver Island's highway network is the Highway 19 which along with a portion of Highway 1 forms the Island Highway. The Island highway is a mix of 4-lane freeway, 4 lane arterial highway and 2 lane highway running roughly along the east shore of Vancouver Island. Access to the west coast of Vancouver Island can be accomplished by crossing mountain passes on Highway 4 to Tofino and Highway 28 to Gold River. Thousands of other roads ranging from small freeways near Victoria to logging roads exist all over the Island.

Although the Sunshine Coast is on the mainland it is connected to the highway network only by ferries. It has one route which is Highway 101, a narrow curvy 2 lane road split in two by a ferry crossing. Texada Island, a large island off the Sunshine Coast and has its own network of highway standard roads although they are unnumbered.

Owing to the challenging topography of the British Columbia Coast, there is no north–south highway linking the coastal communities of the province between Port Hardy and Kitimat. Instead, travellers utilize one of the coastal ferry lines operated by BC Ferries. The exceptions are Bella Coola is accessible by a long largely gravel Highway 20 from the B.C interior over a high pass; and the towns of Terrace, Prince Rupert and Kitimat which is assessed from the B.C. interior on Highway 16.

Haida Gwaii has an extension of Highway 16 on it, one of Haida Gwaii's few paved roads.

Maritime routes

The sheltered waterways of the British Columbia Coast form part of the Inside Passage, a coastal maritime route along which vessels navigate to avoid the rough waters and bad weather of the open North Pacific. As such, the maritime route is heavily trafficked by cruise ships, cargo ships, ferries, and other marine vessels.

BC Ferries, an independently managed publicly-owned company, operates scheduled daily crossings between major population centres throughout the British Columbia Coast. Dozens of smaller ferries ply lesser routes within and between these regions. The Alaska Marine Highway also operates nonstop ferry service through the British Columbia Coast along its Bellingham-Ketchikan route.^[7]

Ports

The Port of Vancouver is the largest commercial shipping port in all of Canada and along the entire Pacific Ocean / Pacific coast of North America by metric tons, which handles a total cargo volume of 76.5 million metric tons.^[8] By the same metric, the Port of Vancouver is also the fifth largest commercial shipping port in North America.^[9]

The Port of Prince Rupert possesses the deepest ice-free natural harbour in North America, and the 3rd deepest natural harbour in the world.^[10] Situated at 54° North, the harbour is the northwesternmost port in North America linked to the continent's railway network. The port is the first inbound and last outbound port of call for some cargo ships travelling between eastern Asia and western North America since it is the closest North American port to key Asian destinations.^[11][12]
