Florida Packing List — What to Bring in Every Season, and the 8 Things Tourists Always Forget

You land at MCO on a Tuesday afternoon in March. You’re wearing the fleece you flew up in from Chicago because the gate area in O’Hare was 58 degrees. By the time you reach the rental-car counter, you’ve sweated through the inner layer and you’re tying the fleece around your waist like a college kid. Outside, the cab line is in full sun. Eighty-three. Humid. Your suitcase has three more fleeces in it.

This is the standard mistake. You packed for the wrong country.

Florida has four seasons, but none of them are the seasons you know. Plan around the calendar you grew up with and you’ll spend the first 48 hours rebuying everything at a CVS at 3am.

The four micro-seasons

Forget winter-spring-summer-fall as you know them. Florida runs on a different clock.

• Winter (Dec–Feb) — Daytime 60–75°F, mornings can drop into the 40s on a cold front. The “best weather in America” months and the reason snowbirds exist. Manatee, birding, and reef trips peak — every spring run is 72°F so the springs are warmer than the air at sunrise. Pack layers, not heat. A fleece, a light puffer, a warm hat for dawn wildlife trips, and a light rain shell.
• Spring (Mar–May) — 70–85°F, humidity still low, almost no rain. This is the “just shorts and a tee” season. Reef-safe SPF 50, polarized sunglasses, a wide-brim hat. The window when you can hike Big Cypress, paddle the Loxahatchee, and snorkel Bahia Honda all in the same week without losing two pounds of water weight per outing.
• Summer (Jun–Sep) — 88–95°F with 75% humidity, daily 2–6pm thunderstorms, and the rainy season proper. Pack quick-dry everything, UPF 50 long-sleeve sun shirts (you will overheat less in long sleeves than in a tee — that’s not a typo, the sun is the load), a cooling towel, a head net for backcountry, a big insulated water bottle, electrolyte packets. Plan your day around dawn and dusk.
• Fall (Oct–Nov) — 70–85°F, humidity dropping, hurricane-season tail. Pack like spring but with a real rain jacket and a flexible itinerary in case a tropical storm forms in the Caribbean. The first cool morning of the year usually lands the third week of October and the locals will talk about it like it’s snow.

The universal pack — every trip, every season

This bag goes with you whether you’re here in February or August. Twelve items, all under $300 total if you don’t already own them:

• Reef-safe SPF 50+ sunscreen. Non-nano zinc oxide. Stream2Sea, Thinksport, Raw Elements. Oxybenzone and octinoxate are illegal in some Florida marine sanctuaries and bad for coral everywhere. Bring two tubes — you’ll go through one a week.
• Polarized sunglasses. Not optional. The sun off Florida water is brighter than anything you’ll see in the Midwest at noon.
• Wide-brim hat or cap. The cap is the bare minimum. A wide-brim is better for half-day kayak trips when there’s no shade.
• UPF 50 long-sleeve sun shirt. One light grey, one navy. Wear it instead of slathering arms in sunscreen every two hours. Saves money and saves the reef.
• Water shoes. Springs are limestone. Jetties are coquina rock and barnacles. Oyster bars are barnacles plus razors. Flip-flops are not water shoes. Get something with a real sole — Astral, Keen, Merrell.
• Insulated water bottle, 32oz minimum. A Yeti or knockoff holds ice for eight hours. A regular plastic bottle hits 95°F by 11am and tastes like a swimming pool.
• Bug spray. DEET 25% or picaridin 20%. Aerosol is TSA-illegal and less effective than the pump bottle anyway. Picaridin doesn’t melt synthetic fabrics, DEET does.
• Small antihistamine + 1% hydrocortisone. Jellyfish brush, no-see-um bites, fire ant. Benadryl + a tube of cortisone solves 90% of trip-ruining itches.
• Quick-dry pack towel. Sea to Summit DryLite. Pack the size of a brick, dries you for a day.
• Headlamp with red filter. Turtle nesting beaches require red light only May–October. Also useful in any campground after sunset.
• Dry bag (10–20L). For phone, wallet, towel, dry change. The cheap Sea to Summit Lightweight version is $25 and lives in your daypack forever.
• Cash. State park gates run $5–10 per vehicle and many are app-only with bad cell signal at the gate. Twenty bucks in singles solves it.

The 8 things tourists always forget

I have walked into the Publix in Key Largo at 11pm three times in the last year to buy these for somebody who didn’t pack one. Pack them.

1. Rain jacket or poncho. The daily 3pm summer thunderstorm catches every first-time visitor. Five-dollar gas-station ponchos rip in the wind. A $30 packable shell lives in your daypack for the rest of the trip.
2. Vinegar spray. A 2oz spray bottle of plain white vinegar is the field treatment for jellyfish and Portuguese man-of-war stings. It deactivates the nematocysts. Urine is folklore and on certain species makes it worse. Carry vinegar.
3. Head net. Everglades, mangrove kayak trips, backcountry hammocks — the no-see-ums at dawn and dusk in summer will end your evening. A $5 head net packs the size of a sandwich and saves the trip.
4. Water shoes. Yes again. People still pack flip-flops only and then walk barefoot across a jetty and end the day in urgent care.
5. Cash for state-park gates. App-only payment looks modern until you have no signal at the booth and a line of cars behind you.
6. Light fleece (in winter). Sunrise manatee tours, January reef trips, dawn birding — Florida’s “warm” can be 48°F at 6am.
7. Cooling towel. Cheap microfiber towel you wet and wring out. Drapes around your neck. Lowers perceived heat by 10°F. The difference between a 4pm meltdown and finishing the trail.
8. Electrolyte mix packets. LMNT, Liquid IV, or any sodium-heavy pack. Drinking plain water in 95°F + 75% humidity can drop your sodium dangerously low. You’ll feel headachy and nauseous by mid-afternoon and think it’s the sun. It isn’t — it’s hyponatremia. The fix is a $1 packet.

What NOT to pack

The luggage you regret is the stuff you brought and didn’t use, plus the back pain getting it through MCO.

• Heavy hiking boots. Florida is hot, wet, and flat. Waterproof trail runners (Hoka Speedgoat, Altra Lone Peak, Salomon X Ultra) breathe better and dry in an afternoon. Boots boil your feet by noon.
• Cotton hiking shirts. They chafe wet, they don’t dry, they hold the salt. Synthetic or merino only. The fast-drying $25 polyester tee from any outdoor store beats your best cotton.
• Aerosol bug spray. TSA confiscates it. Picaridin pump is better anyway.
• Glass containers for the beach. Illegal at most state-park beaches and a hazard everywhere. Cans or hydroflask, never glass.
• Snorkel gear for a one-time trip. Renting at the dive shop costs $15 a day, takes zero suitcase space, and the rental mask actually fits because the staff fit it on you.
• A bathing suit per day. Two is enough. They dry overnight on a balcony rail. You’ll find a third in your bag you forgot about.

Activity-specific add-ons

The base pack covers 80% of trips. Then you add one of these mini-kits depending on what you came for.

• Springs trip: swim shoes (limestone is sharp), swim diaper for toddlers (mandatory at most springs), polarized sunglasses, fleece for after — 72°F water + 75°F air feels cold once you climb out.
• Everglades / backcountry: head net, long sleeves pre-treated with permethrin, binoculars, sun gloves for paddling, more bug spray than you think.
• Snorkel / dive: prescription mask if you wear glasses, 2–3mm shorty wetsuit for Keys winter trips, defog drops or baby shampoo.
• Surf: rash guard, reef booties for low-tide entries, wax matched to water temp (cool/cold for winter, tropical for summer), ding repair kit if you brought your own board.
• Birding: quality binoculars (8x42 or 10x42 — the trinity is Zeiss, Swarovski, Vortex), Merlin Bird ID downloaded with the FL pack pre-installed, a notebook.
• Hiking: trekking poles for the karst limestone (it eats ankles), water shoes for stream crossings on the Florida Trail, an electrolyte tab in your first hour’s water.

Carry-on strategy

Florida airline arrivals delay more than the national average — afternoon thunderstorms close MCO, FLL, and MIA for an hour or two regularly in June through September, and your checked bag may take an extra day to arrive. Pack a survival day in your carry-on:

• One full set of clothes (including underwear and a swimsuit)
• Sunscreen, toiletries, prescription meds
• Phone + laptop chargers
• One pair of sandals
• Reusable water bottle (empty through security, fill at the gate)

If your checked bag goes missing on a 4-day trip, you can run the first 36 hours without it.

Phone setup, before you leave

The Florida outdoor stack is six apps. Install and configure these on the couch at home, not at a trailhead with one bar of signal:

• Merlin Bird ID — Cornell Lab. Download the Florida pack offline.
• Fish Rules FL — official FWC regs in your pocket, no signal needed once cached.
• MyRadar — afternoon storm cells, lightning strikes, the only weather app worth its battery drain.
• NOAA Tides — slack high tide windows for snorkel and shore fishing.
• Google Maps offline — download the whole state park area before you leave Wi-Fi.
• iNaturalist — for plant, snake, and bug ID questions you’ll have within the first hour.

Bookmark the FWC red-tide map (myfwc.com/redtidestatus) and the NOAA Marine Forecast for your stretch of coast.

What it isn’t

Florida is not a desert and it is not the Bahamas. The packing list is not a beach-bag — it’s a full outdoor kit because the state crams a coast, a wetland, a forest, and a spring system into every fifty-mile radius. You’ll do all four in one week without planning to. Pack for all four.

Practical card

• Bag size: carry-on plus one personal item is enough for a 7-day trip. Resist the urge to check.
• The eight rescuers: rain shell, vinegar, head net, water shoes, cash, fleece, cooling towel, electrolyte packets.
• Skip: heavy boots, cotton, aerosol DEET, glass containers, rent-once snorkel gear from home.
• Winter: layers + reef trip wetsuit + warm dawn hat.
• Summer: quick-dry everything + head net + 32oz insulated bottle + electrolyte packets.
• Phone: Merlin, Fish Rules, MyRadar, NOAA Tides, Google Maps offline, iNaturalist.
• In your carry-on: one full day, sunscreen, meds, chargers, swimsuit. Always.

Pack light, pack right, and the only thing you’ll buy at the Key Largo Publix at 11pm is a beer.
