One of the first things people wonder is when is tarpon fishing season in the Florida Keys and Islamorada? When most guides and fishermen here refer to ‘tarpon season’, they really are referring to when the most migrating tarpon show up here in the Keys. During these months we are in ‘tarpon mode’ where most of our clients are coming to target them, and many of us are focused on this type of fishing the majority of the time we’re out. We catch tarpon in the Florida Keys year round, so really the ‘season’ (in regards to good times to catch them) can last much longer then most people think. However there are times when it is more unlikely to have good tarpon fishing, which is mostly due to weather (tarpon don’t like the cold). So what I will do is just go through a run down of each month and what my general feelings are about how tarpon fishing is during that time. Though do remember every year is different – weather patterns are not always predictable, nor are bait migrations or tarpon migrations – so what is a good time one year may not be the next. Also remember conditions change day by day, sometimes hour by hour, so just because fishing wasn’t good one day (or morning) doesn’t mean it won’t be so later or tomorrow. If possible, fishing multiple days will always give you a better opportunity at catching the silver king. So what I am writing is just a general guideline which is all you can really go by for what is the islamorada tarpon fishing season.
January – This is probably the worst month to come tarpon fishing in Islamorada. We usually have our coldest weather of the year during January. Sometimes cold enough that it forces tarpon out of many of the usual haunts to go find warmer water elsewhere. I do not catch many tarpon at this time and would not book a tarpon fishing charter in advance during this month. We have plenty of other types of fishing that are good especially when it is colder. But if it is unseasonably warm and it looks like it’s worth trying, you may get lucky. With the weather these days anything is possible and we’ve definitely had years where we catch tarpon in January given the right conditions. So I would tell anyone in January to book a fishing charter to expect to catch other things, and leave it up to the captain if he thinks it is worth trying.
February – February is usually when I do start to catch a few tarpon semi-regularly. Some years are better then others. I would still probably not tell somebody to specifically come for tarpon this time of year, though you could have a shot at catching one. Chances of cold fronts are still pretty high which isn’t a good thing for tarpon. But if conditions are favorable there is a good chance some fish may be around. Though usually water temperatures are still just warm enough that you may get a bite or two… usually I am not catching a ton of fish this time of year. They are usually larger fish – some of the first arrivals and often they haven’t been ‘messed with’ too much. Most my tarpon fishing this time of year is done on full day trips, where we catch other things like spanish mackerel, ladyfish, and such. We may then spend part of the day after large critters like tarpon and sharks. If it is very calm and warm though I may say things look very good, let’s go all in for tarpon. If it is cold and windy, I’ll probably say it isn’t even worth trying yet.
March – March usually is the start of when we really consider ‘tarpon season’ to be beginning in Islamorada. Chances of cold fronts still exist though usually they aren’t cold enough to totally shut the tarpon bite down, but it may slow it down a bit. We usually have good numbers of migrating tarpon at this point and guides are starting to fish them daily. You can often find tarpon in the backcountry and locally in Islamorada now, so a full day or half day can work. There are often larger fish around at this time of year. The bite still isn’t usually red hot consistently, though you will definitely have your very good days of fishing. A good number of days you may only get a shot or two, usually due to wind or cold, but if you get lucky and have fairly calm weather those will be the big days with a good number of bites. Though where and when the bite is will change, so I always say go with what the captain recommends as far as half day vs full day. The tarpon also are usually not too ‘beat up’ yet either which can be a good thing. Mullet are usually fairly plentiful and tarpon are keying in on them, so I will start fishing with them mainly. Most guides are starting to do a few evening trips, so evening can be a good time to go to beat the crowds on the water. The guys who sell live bait are usually starting to do that sometime in this month, but your captain may have to catch his own bait so hopefully they’ll be able to do that it’s not always easy. March is our windiest month of the year though and it is very busy down here with spring breakers. It can be good fishing but on the exceedingly windy days sometimes that makes it tougher. But overall it’s not a bad time to come.
April – April is one of the primo months for tarpon. We do a lot of live bait fishing locally around Islamorada. Some years the fishing in the backcountry is very good at this time too. The tarpon migration is in full effect with plenty of large tarpon mixed in. The guys who sell bait are usually selling every day at this point and have bait consistently. Some of the best live bait bridge fishing is at this time. The bite can be red hot many days during April. Most guides in town will be tarpon fishing every day during April, and it is one of the busiest months for the evening trips too. April has been some of my best tarpon numbers some years. Though it can still sometimes be fairly windy, and occasionally you get a late cold front but it is unlikely. April is usually a month I recommend though overall for tarpon fishing, and it is one of our busiest months for them. Half days or full days will work, half days we fish the bridges and local channels, full days gives you the option of fishing the backcountry for tarpon too… which sometimes may be better.
May – May is another one of the best months and probably our busiest month in the Florida Keys for tarpon. Most guides whether they are established or not are fishing every day. You usually will have a hard time finding somebody short notice this time of year, though you may be able to for an evening trip as those are generally not quite as busy as the days. Typically the cold fronts are done with which is nice. The winds can still blow somewhat, but you do get a lot more calm days versus the earlier spring. I am usually still doing a lot of fishing around the bridges but start to fish the backcountry more too on my full days… especially when the winds are light. May we often get big number days especially when conditions are ripe (calm, light winds). So in May we get a lot of very good days with plenty of bites. You can still do half day trips but again full days I like because it gives the option of fishing in the backcountry. Bait is still usually fairly easy and the bait guys are selling daily. Some times I start to leave a little earlier on some trips this time of year at 6 AM, especially if fishing has been a little tougher for whatever reason.
June – June is often one of my best months for tarpon fishing as far as number of bites and landed fish go. Summer has officially arrived and there are no more cold fronts. Winds have usually subsided and are often in the 10-15 mph or under range, though of course not always. This usually means that conditions stay relatively the same day in, day out, and are good for tarpon fishing. A lot of migrating fish are starting to move back up north, however, and the resident backcountry fish are often not quite settled in yet and often moving around a lot. I’ll often be locked into a good bite of fish in an area, though at times it dries up and we’re just on the hunt for them… of course I’ll let you know before the trip my feelings on it. I often start fishing the everglades primarly this time of year on my day trips, so I usually recommend at least a 3/4 or full daytrip at this time. The bait guys still do sell some bait for when we do fish locally, which for me is usually just in the evenings. However the mullet are usually starting to thin out in the local areas, and tarpon do start feeding on crabs much more. While you can use crabs usually near dusk and after dark all throughout the year, usually by June they can work better even before sunset. I primarily am wanting to leave the dock early this time of year by 6 AM, and the bait catching in the everglades usually gets fairly consistent at this time and so does the fishing.
July – July is similar to june, however the tarpon often are in much more predictable patterns and ‘settled in’ to the summer time conditions. Though the business is usually starting to slow down a little bit. I myself still fish a fair amount in July, especially since the tarpon fishing can still be very very good. With the good fishing and having a lot of it to myself, July is one of my favorite months to fish for tarpon. Some will tell you it’s gotten too hot though that just isn’t true. If you make the far runs as I like to do into the everglades the day time fishing can be red hot this time of year. Evening trips are still productive fishing crabs or even dead bait, usually the live mullet fishing isn’t quite as good as it is in the spring. Sometimes even going after dark is a good bet at this time especially to beat the heat. Though pilchards, if you can find them, can work wonders especially during the daylight hours around the local bridges and channels. But for me I am usually dialed in on my full day backcountry fishing for tarpon at this time. Many of the migrating tarpon have moved on in July, so we don’t catch as many 100+ lbers, but many in the 30 to 80 lb range. Usually the bait guys are done for catching and selling live mullet at this time, but if you are someone like me that primarily tarpon fishes I am still catching them daily in the backcountry. 3/4 or full days are recommended and early 6 AM departures as well.
August – August can still be very good for tarpon fishing in the everglades, though it usually isn’t quite as consistent as July. The weather is usually nice and calm which is for me probably the most important factor for good tarpon fishing. Also there aren’t many other boats on the water to worry about so you get the place all to yourself usually. Some years I’ve had very good fishing all through August, other years it comes and goes in spurts. But overall I still like August a lot, probably more so than the early spring due to the nice weather. The local fishing can still be OK especially in the evenings but by this time many guides including myself are a little burned out so we aren’t doing too many evening trips any more. 3/4 or full days are recommended for myself, and early 6 AM departures as well. Much of the fishing I do this time of year is further back in the Everglades, so a full day is even better.
September – September is always a slow month in the Keys and one of my least busy. However the conditions can be very good for tarpon fishing still, as barring a hurricane it’s usually fairly calm and warm. The other nice thing is you have the place all to yourself and you won’t often see another boat on the water. Though even the resident fish this time of year can be more hit and miss. I’m usually not fishing very much at this time, so usually if we do go I don’t always have that ‘day to day’ knowledge that I have earlier in the season when I’m fishing 5 to 7 days a week. So if we tarpon fish sometimes we are just having to go fish areas and see what’s there, put some time in, and hope for the best. Some times we may get lucky and find hungry fish in the first place we stop, other times you may have to check multiple areas. So obviously having time helps… I would recommend a full day if you are serious about it. I’ve had some of my best tarpon fishing of the year in September certain years, and others… it’s been a grind.
October – October can be very good for tarpon fishing as we usually get the ‘fall bait run’ going on. Many tarpon are starting to make their way back south as it’s cooling off further north. It’s not as consistent as the spring run… some years we get lots of bait and tarpon going crazy crashing them in the everglades. Other years the bait just doesn’t push this far down and you don’t see all that crazy action. But it is usually still fairly good conditions and things have cooled off just a hair from the dead heat of summer. Some years I’ve had some of the best tarpon fishing of the year in October. It’s busier then September, but still fairly slow. I like fishing this time of year and it’s usually a good shot at getting a tarpon, and sometimes some larger fish can be showing back up too before the winter. 3/4 or full days usually recommended, though if bait is around locally sometimes you can have good local bridge/channel fishing and do a half day… but my routine is usually more in the everglades so I’ll usually recommend a longer trip to do that.
November – November is usually not a great month for tarpon fishing, but sometimes its OK. We usually start to get some cold fronts and northerly wind which tarpon do not like. Though not always… If it is still warm and summer-like conditions, tarpon are possible and there will always be a few residents around. I’m not usually fishing for them a whole lot though as we are often doing more backcountry mixed bag stuff, so similar to September if you want to go it may be a bit of looking around and just trying areas. I would usually not book a trip in advance really focused on tarpon at this time, but if you are OK with targeting other things and perhaps trying tarpon for part of the day if conditions look good, that’d be a better idea.
December – December I usually do not do a whole lot of tarpon fishing. Cold fronts are much more likely. Christmas week is always crazy busy. But before that isn’t so busy. Similar to November, if it is unseasonably warm tarpon are possible. Though I’m likely not targeting them too much so not dialed in with the bite. Probably best to book with the idea of catching other things and again if it looks reasonable, perhaps try it for part of the day. But like January, if it is unseasonably warm it may be good.
So there you have it that is my run down, month to month, of the best months for tarpon fishing season in Islamorada. Obviously booking a trip ahead of time you just can’t predict many of the conditions such as wind, temperature, whats happening with the bait and fish migrations, etc… Though one thing you can also know ahead of time is moon phases. I don’t particularly like full moons for tarpon fishing, especially during the daylight hours. I think the fish sometimes gorge themselves at night and can be very finicky during the day. Though not always… but if you are planning your trip months in advance, this is the one other thing that you can have a little control over. Try to avoid it.
That’s really the best advice I can give for booking ahead of time. If you’d like more information feel free to contact me directly!
