The snook are not considered a "catch and release". It depends on Mr. GreenJeans and how his day is going. He may consider it "harrassment" of a game fish. (personally, I would not target a non-season game fish just for sport). Just let them enjoy their "time off" so they can relax and reproduce in peace.
As for fishing in July - Impossible to predict anything that far in advance. Really depends on the storms and potential hurricanes this summer. PLUS - the sargassum seaweed is making landfall on our East Coast and will only get worse with the onshore winds and tides.
