Jersey Shore in December

July and August bring peak crowds, peak prices, and peak fun. Ocean temperatures hit 70°F, every boardwalk attraction runs full schedule, and the energy is infectious. But parking costs $30-40 daily near popular beaches, and restaurants have hour-long waits. June and September offer the best compromise - warm enough for swimming, fewer crowds, and shoulder-season hotel rates. May brings mild weather perfect for boardwalk walks, though ocean temps stay around 60°F. October can surprise you with 70-degree days, and most attractions stay open through Halloween. Winter shuts down most boardwalks except Atlantic City, though Point Pleasant Beach keeps some restaurants and shops open year-round.
