The longest east coast wave is probably in maine or new hampshire. Probably a wave that hardly ever breaks, but on the right conditions will offer up some insanely long rides. The coast up there is just suited for longer waves, to many points and coves to count. The mid atlantic is mostly sandy, and sand bottoms just shift to much to really offer up long point style waves.
Grew up surfing Sandy Hook NJ in the 70's - 80's and those jetties, before the armycorp ruined them offered some of the longest waves around. 1st Jetty could be the most perfect wave I have ever surfed. Unfortunately they are all under the sand right now and unless funding goes bankrupt they will not be seen again for a long long time. The cove "at the Hook" as it is now is nothing like it was back then, and hardly worth checking anymore. All of the great surf spots in northern Monmouth County have been ruined, The wall in Long Branch, Seven Presidents, Bradley Beach and Belmar were all great and are now mediocre at best. We all need a time machine to go back 20 years and ride those waves like they were.
just when long branch was starting to get a littleeeeeeee better, but nothing like it was..they just ruin it...the pit is never gonna be like it was..never
Right out of college I got a job as a hydrographic surveyor at a company named Weeks Marine; Little did I know they were in the business of destroying surf breaks. The main blame can be put on Monmouth County and the USACE for giving us the contract for the beach replenishment job. I have surfed some of those breaks and remember how good they were. Just to let you know I don't work for them any more. Back to the question at hand, the longest EC wave. How about Reef Road in FL. I've surfed it on a solid NE swell and thats a pretty long ass wave.
SeaDaddy, that's funny I once talked to a guy up in Belmar who was clearly working for whoever was doing work with the pumping. I asked what was going on out there and he said they were surveying before work began on beach replenishment. He clearly felt guilty about what was going on and I imagine I wasn't the first person to approach him. There was no hostility in me and I felt for the guy being the one stuck on land while every surfer who knew enough was probably telling him off. I knew what had been done to Sandy Hook and Seabright but still felt sorry for the people who had to carry out those orders. I have a friend that has surfed reef road and he said the same thing, fun long wave. I can't imagine anything beating Nova Scotia on the East coast. That water up there is cold pretty much all year and I can't imagine paddling out in the winter on a big swell up there. I got hit by 3 waist high waves in a row down here last week and my skull felt like it was cracking.
