What is known about the Salish Sea?

The Salish Sea, located in the coastal region of the Pacific Northwest in Canada and the United States, experiences relatively cold water temperatures throughout the year due to its proximity to the Pacific Ocean. In the winter months, from December to February, water temperatures typically range from 42–48°F (6–9°C), which can feel very chilly for swimming without a wetsuit. In the warmer months, from June to September, the temperature rises slightly to 54–60°F (12–16°C), still on the cooler side but more tolerable for those used to colder waters.

Swimming in the Salish Sea is possible, especially in the summer months, though the cold water temperatures can be a challenge for many. Popular areas for swimming include parts of Vancouver Island and the San Juan Islands, where calmer waters and picturesque coastlines provide a pleasant setting for beachgoers. While the water may not be as warm as in tropical regions, it is ideal for swimming, kayaking, and paddleboarding, especially for those who enjoy a refreshing dip. Some swimmers opt to wear wetsuits to stay comfortable, particularly in the cooler months. The sea is also known for its abundant marine life, which makes it a popular destination for snorkeling and scuba diving, where the cool waters provide a unique opportunity to explore vibrant underwater ecosystems.
