What to Pack for Costa Rica Rainy Season: Must-Haves

If you’re visiting Costa Rica during the rainy season (especially in places like La Fortuna or Monteverde), you’re almost guaranteed to get caught in a sudden downpour. The rain usually doesn’t last long, but it can come out of nowhere and soak you fast. These essentials kept me dry, comfortable, and ready for whatever the jungle threw my way. Tip: Check the Costa Rica weather forecast before you leave to get a sense of what to expect. Rain can vary a lot by region and season.

Lightweight Rain Jacket (with hood)

Look for something waterproof, breathable, and easy to pack. A good rain jacket is a non-negotiable if you’re planning hikes, ziplining, or exploring near waterfalls. I brought this one and it folded right into my daypack.

Quick-Dry Clothes

Cotton stays soggy forever in humidity. You’ll want lightweight, quick-dry shirts, leggings, or shorts that are breathable and can handle a little sweat or rain. I rotated through 2 outfits and washed them in the sink when needed.

Waterproof Shoes or Sandals

If you’re doing any hiking or exploring near rivers or mud, closed-toe waterproof hiking shoes or durable sandals like Tevas or Chacos are clutch. Flip-flops won’t cut it for most outdoor activities. I brought these with me and absolutely loved them. Not only were they light weight but they’re quick-dry and easy to hike in,

Dry Bag or Waterproof Backpack Cover

Even if your backpack isn’t waterproof, you can toss a dry bag inside for electronics or use a backpack cover during rain showers. It saved my phone and extra clothes more than once.

Rain Cover for Camera Gear

As a photographer, I was glad I packed a rain cover for my camera. The weather can shift fast, and having protection meant I could still shoot in misty, wet conditions without worrying about water damage.

What to Pack for Costa Rica Day Trips & Jungle Adventures

Small Daypack or Foldable Backpack

You’ll want something lightweight to carry your essentials (water, sunscreen, camera, snacks) without being bulky. I used a packable daypack that folded into my suitcase and brought it everywhere.

Waterproof Phone Pouch

Perfect for hot springs, boat tours, or sudden rain. It gave me peace of mind knowing my phone was safe while I was snapping photos or getting splashed. This was also great for many other trips where I was able to snap some pics underwater.

Swimsuit + Microfiber Towel

Always have a swimsuit on hand—random swimming spots will happen. A quick-dry towel is also super useful for hot springs, beaches, or rain.

Sunscreen & Bug Spray

The UV in Costa Rica is no joke, even when it’s cloudy. Go for reef-safe sunscreen if you’ll be in natural water sources, and bug spray is a must for the jungle or dusk outings.

Reusable Water Bottle

It’s hot and humid, and you’ll want to stay hydrated. I refilled mine constantly and loved having one with a built-in filter.

Costa Rica Packing Tips (and What I Wish I’d Brought)

Even though I packed pretty light, there were still a few things I either forgot or didn’t realize would be so useful until I got there. If it’s your first time traveling to Costa Rica, these tips might save you from overpacking—or from kicking yourself halfway through the trip like I did.

Don’t Overpack

Most people wear the same 3–4 outfits on rotation, especially if you’re backpacking or moving around a lot. Bring less than you think you need. You’ll be hot, sweaty, and living in quick-dry clothes anyway.

Bring an Extra Pair of Lightweight Shoes

I had my main pair of waterproof shoes, but I wish I’d packed a second pair of comfy sandals for when the first got wet or muddy. Having a dry option makes a big difference.

Portable Charger = Lifesaver

If you’re out for full-day tours or bouncing between towns, your phone battery will drain fast. I forgot mine at home and really regretted it.

A Few “Cute but Functional” Outfits

You don’t need a full glam wardrobe, but I wished I had one or two slightly nicer outfits for dinner or photos—especially with the backdrop of volcanoes, waterfalls, or sunsets. Just make sure they’re still breathable and easy to walk in.
