In the event that you are a surfing beginner you should think about borrowing the surf equipment from a friend or renting it. Never buy expensive equipment available everywhere and constantly advertised. You can always end up not enjoying practicing surfing. Also, you will see that new boards and good wetsuits are quite expensive. You should analyze the fact that beginners are not to purchase shortboards and a longboard will be replaced after you do learn so it could turn into wasted money.
A longboard is the most needed surfing equipment that any beginner surfer needs. One board, larger than 8 feet is preferred. Foam longboards guarantee that you are to catch waves easily and avoid some possible injuries. When you are just beginning size stands out as important.
Now when referring to a wetsuit we need to take a close look at your personal budget. A discussion with local surfers is going to show you exactly what is needed. Fortunately for most surfers they will only need complete wetsuits when swimming in colder environments. If not then you can do well with just boardshorts in your surf equipment. In the event that you think you will surf for longer periods of time you might want to consider purchasing one good wetsuit.
A surfing equipment that includes swimming gear and a board is basically what you really need. You might want to think about investing in a surfboard leash. Alternatively there is also the possibility of investing into surf wax in the event that you do not rent a board. All the extra surf equipment recommended by others is actually optional. You can look at a surf shop to see what else you could buy but this is something that you will do as time passes. Once you purchase/rent basic surf equipment you should not think about a lot more.
