Channel Islands in October: what the park service says

October is often the calmest month on the water. The park's kayaking page names August through October as the time with the gentlest winds and seas, and the weather page says early fall can bring the ocean close to 70°F with underwater visibility reaching 100 feet, which suits snorkeling and paddling to the sea caves. The catch is that strong east or Santa Ana winds become possible from about October on. The no-entry pelican closure around West Anacapa ends on October 31, and the park says western gull movements away from the colonies peak this month. Inside the sea caves you may not leave your kayak, and some beaches stay closed to landing for seals and seabirds.
