Los Angeles is said to have summer all year round. Everyday is a beach day and very seldom are chilly temperatures experienced – even in winter! So anytime you can have a holiday experience.
All year round is the best time to visit Los Angeles. Most people plan their trips around specific events because the weather is pretty much stable as warm, hot or mild. So your trip schedule or travel time is determined by the events more than by the weather. All you need to do is to make sure that you organize and plan your trip.
