When selecting a rod for surf fishing, you need to think about the area you will be fishing and what types of fish you will be catching. If you are fishing from the beach, a longer rod will help you cast further and keep your line above the incoming waves. A longer, heavier rod will also help you land some of the bigger fish that come out of the surf. If you are fishing for smaller fish such as whiting, then you will be fine with a shorter rod. It is just a little easier to make longer casts and keep your bait positioned in the same spot with a longer rod.
