Almost one million people from the region are expected to travel for the holiday and the Jersey Shore is one of the most popular destinations.
"We drive. It's about seven and a half hours if you drive through the middle of the night with two kids - nine stops. Hey, well worth it," said Sam Rehfus who traveled with his family from Kenton, Ohio.
As folks made it to the shore on Wednesday, they were greeted with sunny blue skies and no lines - just yet - on the boardwalk.
"This is our first time here for the both of us - first time. It's fantastic, nice and clean. The water is rough," said Leslie Pernsley of Fern Rock.
While people cool off in the water officials are urging beachgoers to be safe and to only swim when lifeguards are on duty.
Nine people were rescued off the 9th Street jetty last weekend after they were walking along rocks and fell in.

Beachgoers are excited for the summer holiday to kick off.
"We're looking forward to the fireworks tomorrow night. Come out on the beach, check 'em out, hoping for good weather," said Erik Vermullen from Blackwood.
"It doesn't get more Jersey and better than this for the kids. We've gone every year, and we love it," added Mayline Vermullen.
Officials want to remind people to only go in the water when lifeguards are on duty, which is at 10 a.m.
Fireworks on Thursday night on the boardwalk are scheduled to start at 9:30 p.m.
