Huntington Beach is world-famous as "Surf City", from the 1960's Jan and Dean surf rock song of the same name, and much of surfing culture started and continues to evolve there, from surfing styles to surfing apparel companies that started there.
The year round temperature averages 67 degrees F, and good weather can be found year-round. However, the months of January to March can be rainy.
Long Beach Airport is also within close distance but has very little service from only four carriers. JetBlue Airways  serves nine destinations from Long Beach: Oakland, Sacramento, Salt Lake City, Las Vegas, Chicago (O'Hare), Boston, New York (JFK), Washington (Dulles), and Fort Lauderdale.
Los Angeles International Airport (LAX)  is the largest airport in the area.
Huntington Beach is located at the intersection of Beach Boulevard and the Pacific Coast Highway, just directly south of Knott's Berry Farm in Buena Park.
Parking: The best place to park is the city parking located right at the beach. The entrance is just north of Highway 1 (the PCH) and the main street. You will conveniently be able to unload watercoolers, surf boards and the kids all safely without having to cross streets. It saves on lifting and lugging as well. You can wash off and change clothes right next to the parking at the water showers and washrooms. Washrooms are adequate but small. They also get wet and sandy during the day.
OCTA Route 1* North and South runs along the Pacific Coast Highway, servicing all of Orange County's beaches. Routes 33 and 35 South directly run into Huntington State Beach.

Huntington Beach boasts the largest unspoiled coastal wetlands in California, Bolsa Chica Wetlands, where many migratory birds stop and nest.
Huntington Beach has some of the largest stretches of open-sand beaches in all of California, as well the Huntington Beach Pier (one of the longest concrete piers in the world), site of world-class surfing and volleyball events yearly.
Running/Walking/biking/rollerblading: There is a wide boardwalk right by the pier. It is part of the Huntington Beach Bike Path. The Bike Path runs for about eight miles along the beach. Heading south along the boardwalk is likely your best scenic scenario. Walking, riding a bike, running are all very safe. Many very good runners first thing in the morning - often as soon as the sun comes up.
Surfing: You can try your hand at surfing. There is a surf rental shop right at the boardwalk. Start with a boogie board for the day circa $15 US. Many good surfers so they may get annoyed if you stand in the waves too long. Keep moving is your best bet. If you get tired get out (of their way) by heading to the hot sandy beach to rest up for more.
Relaxing:Take a walk up the main street. There is a number of restrauants and a starbucks.
Peak season is from late May to early September. The beaches on any given summer day may have as many as 500,000 visitors when it is particularly hot inland.

Crime is very low for such a large city, and violent crime is very rare. If you are drinking, you should be far more concerned with local police than civilians. Huntington Beach police have a vigilant reputation regarding DUI enforcement, so call a cab.
