On the water

VERY COLD water year-round (4-12°C/39-54°F in summer) — dry suit MANDATORY with neoprene hood, gloves, and booties. The bottom is sandy and muddy. Large tidal range (up to 8 meters/26 feet) creating vast mudflats at low tide. Significant tidal currents. Water is glacial and turbid. The water can be choppy in westerly winds. Sandbars shifting with tides.

Hazards

Glacial water — hypothermia in minutes without a dry suit. Extreme tidal range — extensive mudflats at low tide, risk of getting stuck. Strong tidal currents. Wildlife: brown bears frequent on beaches, never leave food or gear unattended. Sea otters, seals, sea lions in the water. Whales (orcas, humpbacks) in the bay. Turbid water — zero underwater visibility. Weather conditions changing rapidly. Limited rescue services.
