The most common place to find squid is around seagrass in calm water. Squid lay their eggs in weeds so targeting seagrass or weed beds is a popular spot.  They aren’t frequently found in water shallower than 6 feet deep like a sandy beach.  Squid are fussy around murky water as well as changes in salinity.   ​Squid are a schooling species so if you catch one you are likely to catch many. Keep moving around until you find their school.  Squid are also commonly found around docks and bridges. They are attracted to the permanent lighting at night. Fishing after dark for squid down at your local bridge over deep water is a good option.
