This comprehensive guide breaks down the weather month by month, helping you plan the perfect getaway or simply appreciate the climate of this coastal paradise.

Overview of Newport Beach’s Climate

Newport Beach enjoys a Mediterranean climate characterized by warm, dry summers and mild, wetter winters.
