Introduction
One of the biggest questions anglers ask before planning a trip is, “What fish are biting right now?” The Florida Keys offer excellent fishing opportunities throughout the year, but certain species are more active during specific seasons.
This guide breaks down the best times to target some of the most popular game fish in the Florida Keys.
Spring (March – May)
Spring is one of the best fishing seasons in the Keys. Water temperatures begin to rise, bait becomes more abundant, and many species become increasingly active.
Popular spring targets include:
- Mahi-Mahi
- Yellowtail Snapper
- Mangrove Snapper
- Blackfin Tuna
- Tarpon
- Kingfish
Tarpon fishing begins to heat up during the spring months, especially around bridges and channels throughout the Keys.
Summer (June – August)
Summer offers excellent offshore fishing opportunities. Calm seas and warm water bring a variety of pelagic species within range.
Popular summer targets include:
- Mahi-Mahi
- Blackfin Tuna
- Wahoo
- Yellowtail Snapper
- Mangrove Snapper
- Mutton Snapper
Many anglers also target deep-water species such as snowy grouper and tilefish during the summer when weather conditions allow for long offshore runs.
Fall (September – November)
Fall is often overlooked but can provide outstanding fishing with less boat traffic.
Popular fall targets include:
- Mangrove Snapper
- Grouper
- Kingfish
- Blackfin Tuna
- Yellowtail Snapper
Cooling water temperatures often trigger increased feeding activity among reef and offshore species.
Winter (December – February)
Winter brings cooler temperatures and some of the best reef fishing of the year.
Popular winter targets include:
- Yellowtail Snapper
- Mangrove Snapper
- Grouper
- Mackerel
- Sailfish
- Blackfin Tuna
Cold fronts can create excellent opportunities for sailfish along the reef edge.

Several species can be caught throughout most of the year in the Florida Keys:
Mangrove Snapper
Mangrove snapper are one of the most reliable species in the Keys and can be found around bridges, docks, mangroves, reefs, and wrecks.
Yellowtail Snapper
Yellowtail snapper provide excellent action year-round, especially on patch reefs and offshore reef structures.
Blackfin Tuna
While peak seasons exist, blackfin tuna can be encountered throughout much of the year depending on water conditions and bait concentrations.
Final Thoughts
