What to Pack for a Trip to the Florida Keys

The Keys are a trip spent in, on or beside water, so sun protection and quick-drying gear matter more than outfit count. The most effective move is covering up with UPF clothing rather than relying on sunscreen alone. And one widely repeated rule about reef-safe sunscreen is not actually a rule.

Quick Answer

Why coverage beats sunscreen here

The default advice for a beach trip is more sunscreen. In the Keys the better answer is clothing that does the work, because you will be outdoors all day and often in the water, where sunscreen washes off and needs constant reapplication. A rash guard or UPF long-sleeve shirt gives continuous protection, and a wide-brim hat covers your face far more effectively than a cap.

That shifts what goes in the bag. Swimwear is the real wardrobe here, and two suits minimum is the standard advice, because pulling on a damp one is miserable when you are swimming daily. A sarong or light cover-up is the most versatile single item you can carry: swim cover-up, impromptu towel, beach mat, head wrap, and a layer for restaurants that run their air conditioning cold.

Footwear is simpler than most destinations but has one specific requirement. Flip-flops and comfortable sandals cover town, and the islands are walkable enough that you need fewer shoes than you think. Water shoes are the exception worth packing, because much of the Keys shoreline is rocky and coral-strewn rather than soft sand.

Two small items solve outsized problems. A dry bag keeps a phone and wallet usable through boat trips, kayaking and unexpected swells. And insect repellent matters for evenings and after rain rather than all day, which is also why light-coloured clothing is worth choosing: it reflects heat and is less attractive to mosquitoes than black or navy.

Rain here is brief and intense rather than persistent, so a poncho or compact umbrella handles it without carrying serious rain gear. Dress standards are as casual as anywhere in the country, with loud patterns entirely welcome, though a few nicer restaurants prefer a collared shirt. If you want the deeper version of the fabric reasoning for humid climates, our Costa Rica packing list works through it.

Common Mistakes

People rely on sunscreen alone. In practice UPF clothing protects better, because sunscreen washes off in water and rarely gets reapplied often enough.

People bring one swimsuit. In practice you will want two or three, because humidity slows drying and you may swim more than once a day.

People skip water shoes. In practice rocky and coral shorelines cut feet easily, because much of the Keys coast is not soft sand.

People pack heavy fabrics. In practice thick cotton, wool and leather are unwearable there, because humidity stays high in every month of the year.

People assume mosquitoes are constant. In practice they appear mainly in the evenings and after rain, so repellent is a targeted item rather than something you wear all day.

The reef-safe sunscreen rule that is not a rule

This is the correction worth knowing, because a great many Keys packing lists state it incorrectly. Key West's city commission did pass an ordinance banning the sale of sunscreens containing oxybenzone and octinoxate, voted through in 2019 and due to take effect on 1 January 2021.

It never took effect. Florida's legislature passed SB 172, preempting local regulation of over-the-counter drugs and cosmetics, and the governor signed it in 2020, effective that July. That law overrode the Key West ordinance before its start date and blocked similar local bans elsewhere in the state. You can read Surfrider's account of the preemption fight for the background.

So the practical position is this: chemical sunscreens are still sold in Key West, nobody will check your bottle, and choosing mineral sunscreen is a decision rather than a requirement. The reason to do it anyway is that the Keys sit alongside the only living coral barrier reef in the continental United States, and oxybenzone and octinoxate are widely documented as harmful to coral. Look for zinc oxide or titanium dioxide on the ingredient list rather than trusting the words on the front of the bottle, since "reef safe" is not a regulated term.

Laws change, and this one has already changed once, so check the current position if it matters to you rather than trusting a packing article, this one included.

A trip where one bag covers a snorkel morning, a boat afternoon, a sudden storm and a casual dinner is more variable than a beach holiday sounds. That kind of overlap is what JetKit is built to reason through, so what you pack matches the days you will actually have.
