Common questions

Channel Islands month by month: notes from the park service

• January: January is the middle of the wet season at Channel Islands. The park service says most rain falls between December and March, with sunny, clear days between storms, and ocean water drops to the low 50s in winter.
• February: February is the tail of the wet season and the best stretch for gray whales: the park service says they are the most common sighting from mid- to late December through mid-March, while common dolphins are around all year. Watch from a boat with Island Packers or another operator out of Santa Barbara, Ventura or Channel Islands Harbor, or from land; the Ventura visitor center has a tower with telescopes.
• March: March closes the gray whale window, which the park puts at mid-March, and opens spring. The weather page warns that spring stays windy even as it warms, with sea temperatures from the mid 50s to the low 60s.
• April: April is nesting time. West Anacapa and Santa Barbara hold the only brown pelican breeding colonies in the western United States, and on Santa Barbara Island the nesting area is closed and trails shut while birds sit on eggs.
• May: May belongs to the western gulls. The islets of Anacapa hold the largest protected breeding colony of the species in the world, with more than 10,000 birds gathering to nest from May through July, and females lay two or three olive-green, dark-marked eggs in late April or May.
• October: 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.
• November: November falls between the calm fall seas and the winter storms. The water is cooling from its autumn high, and Santa Ana or east winds remain a risk; the kayaking page adds that forty-knot winds are not unusual around Santa Rosa and San Miguel.
• December: December starts the rainy season at Channel Islands: the park service says most rain falls between December and March, with clear, sunny days between storms. The islands can only be reached by boat, and Island Packers runs public boats year-round from Ventura Harbor and Channel Islands Harbor.
