Officials say while there will be some adjustments this year, the tradition will largely be the same, which means the city will get a view of the Blue Angels and the parade of ships.
Law enforcement agencies say they will be out in force, at all the venues and events, across the city.
"We're going to ensure that we have staff out there," said Sheriff Paul Miyamoto. "Our plain clothed staff will be in uniform, our people will be out there working with the police department, because the most important thing is to be a viable deterrent to any shenanigans, any tom-foolery that may occur."
