ABOUT JULY
Because July is one of Florida’s hottest months you should start fishing as early as possible or even fish at night. The tides will determine how you fish. If it is low tides in the morning head to the backcountry and look for tailing redfish along oyster bars and grass lines, to the edges of the mud flats. Reds can be skittish in shallow water so use small lures and caution. If the tide is on the higher side in the morning look for trout, in addition to redfish. As the day progresses go deeper to cooler water in mid-day. After 10:00 in the morning the breeze picks up and the sun gets high the bite slows.
Tarpon
Tarpon within casting distance of the beach are being taken using live whiting as bait. The St Marys Jetties the St Johns Jetties and Nassau Sound are also great spots to target tarpon in July. Fishing tide rips off Nassau Sound can be productive for both tarpon and jack crevalle. Chumming off the beach is a good trick to entice tarpon along with plenty of shares and jack crevalle.
Flounder 
Live finger mullet, mud minnow or white Gulp Swimming Mullet on a popping cork or jig fished slowly over a mud bottom is the ticket for flounder. Fort Clinch rock jetties and around piers and any number of creeks mouths in northeast Florida will produce well.
Surf
See tarpon above.
The outgoing tide has been good for whiting and pompano for anglers using clam, shrimp, sand fleas, and Fishbite baits. Clear water is the key to good fishing along the beaches. The occasional trout, redfish and black drum will be taken from the beach.
Trout & Redfish
July is a good month to try night fishing for trout and redfish. Fish slowly and methodically, using lipped-diving plugs. Fish are most active during the first of the falling tide.
