Typically, March on Santa Catalina Island offers a transition from winter to spring. Visitors can expect daytime temperatures averaging in the mid-60s Fahrenheit (around 18 degrees Celsius), with nighttime lows dipping into the 50s Fahrenheit (around 10-15 degrees Celsius). Rainfall is possible, though less frequent than in the preceding winter months. Ocean temperatures remain cool, generally in the low to mid-60s Fahrenheit.
Understanding the prevalent climatic conditions during this period is crucial for planning a successful trip. Packing layers of clothing allows visitors to adjust to fluctuating temperatures throughout the day. The moderate climate makes March an ideal time for outdoor activities such as hiking and exploring the island’s unique flora and fauna, while the potential for calmer seas opens opportunities for water activities like kayaking and boat tours. Historically, March marks the beginning of the island’s busy season as tourists seek pleasant weather before the summer crowds.
