About Channel Islands Weather

The Channel Islands have a Mediterranean climate year-round. Temperatures are relatively stable. However, visitors must be prepared for high winds, fog, rough seas, and sea spray at any time. Winds are often calm in the early morning and increase during the afternoon. High winds may occur regardless of the forecast, especially on the outer islands, Santa Rosa and San Miguel. Anacapa, eastern Santa Cruz, and Santa Barbara Islands have more moderate winds. Dense fog is common during the late spring and early summer months, but may occur at any time. Nearly all precipitation occurs in the winter, with the summers being extremely dry. Ocean water temperatures range from 50°F in the winter to nearly 70°F in the fall.
