As an out of state student your tuition will be very expensive. Housing is also very expensive. A 1-bedroom apartment with very few amenities in a safe area will rent for over $1000 a month.
There is no surfing in Long Beach due to the breakwater which protects the port. There is surfing in neighboring Seal Beach and Huntington Beach. Seal Beach is a very cute and safe town, which makes it more expensive.
Long Beach is a city of 500,000 people that covers 50 square miles. If you do the math that a lot of people per square mile. It's very diverse, compact, busy and noisy. You name it, we got it. Rich, poor, middle class, gay, straight and every ethnic group.
We've got plenty of bars and live music venues. Country, hip-hop, punk and everything in between.
Belmont Shore (it's not Shores) has plenty of good shopping, bars and restaurants. It's also a cute neighborhood to live in. If you like artsy scenes than 4th Street 'Retro Row', East Village Arts District and Bixby Knolls First Fridays are some places you should visit. There are tons of festivals and arts related events in LBC. The Art Theater on 4th Street shows art house movies in an old Art Deco theater. Most of the bars in Long Beach tend to be dive bars with lots of hipster scum in them.
A lot of people smoke marijuana here. As a non-native I'm surprised to see people walking down the street smoking weed or smell weed while I'm walking down the street.
I live in a historic neighborhood by the beach and it's the type of place where everyone looks out for each other. People say 'hello' when they walk by you and there are always plenty of people skateboarding, biking, jogging and out enjoying the weather.
There are plenty of crappy of neighborhoods in Long Beach though. Look up //www.meganslaw.ca.gov/ and you'll see there are a huge number of registered sex offenders in some neighborhoods. Obviously you should avoid those.
There are a lot of homeless and trash diggers in Long Beach and Southern California. For the most part they're harmless.
To sum it up. If you have the money, being young and single in Long Beach is pretty good.
