Mahi stay on the menu, the reef fishes best after dark, and the Keys briefly lose their minds for two days of mini lobster season.
July keeps the mahi coming, with dawn patrols beating both the heat and the afternoon thunderheads. The fish average smaller than June's but the action stays honest, and the early boat gets the calm ocean.
The reef flips its schedule: the yellowtail bite goes nocturnal-good at dusk, and the evening shark trip earns its keep with tax-collector blacktips and bulls prowling the same edges. Ask about the late-day runs.
The two-day sport lobster season lands in late July and the whole state drives south for it. Book boats and rooms far ahead that week, or fish the week after when the water empties out.
Mornings are genuinely pleasant on the water. The move is an early half day, back before the afternoon storms organize.
A two-day sport season in late July. It is the busiest boating week of summer; plan around it or well ahead of it.
Some of the best: shark action at golden hour and snapper chewing after dark, all in cooler air.
