Costa Rica is a small country with enormous climate variation — a single week can include Pacific beaches at 90°F with 70% humidity, cloud forests at 55°F and wet, volcano slopes with temperature swings of 40°F between day and night, and Caribbean coast conditions that are different from the Pacific side. Layering this into a single packing list requires more thought than typical beach-destination packing, and the rainy season vs dry season split compounds the complexity.
This guide covers packing for a one-to-two-week Costa Rica trip in either season, with notes for specific regions (Pacific coast, Caribbean coast, cloud forest/Monteverde, Arenal/Northern Lowlands).
Dry season vs rainy season
Dry season (December-April): The tourist high season. Sunny most days with low humidity on the Pacific side, still warm and humid at beaches. Daily highs 75-95°F depending on elevation. Rain is brief and scattered. This is the default “good weather” window.
Rainy season (May-November): Called “green season” locally. Mornings are often sunny and clear; afternoon thunderstorms are frequent and intense (1-3 hours of heavy rain). Lower prices, fewer crowds, lusher landscapes. September and October are the wettest months and worst for beach trips but excellent for wildlife viewing.
Temperature note: Costa Rica is tropical — temperature varies more with elevation than with season. San José (3,800 ft) is 65-80°F year-round. Monteverde cloud forest (4,600 ft) is 55-70°F with mist. Coastal areas are 75-95°F year-round.
Tops (pack 5-7)
3-4 quick-dry t-shirts or tanks: Merino, polyester/elastane, or nylon blend. Cotton becomes damp and heavy in tropical humidity and stays damp for hours. Quick-dry fabric transforms humid-day comfort. See our quick-dry fabrics guide for fiber science.
1-2 long-sleeve UPF shirts: Sun protection on beach days, mosquito protection at dusk, coolness in shaded forest trails. Light colors reflect heat better. Look for UPF 30+; see our UPF ratings guide.
1 nicer top: For dinner at one of the better beach-town restaurants. Linen shirt, merino polo, or a breathable blouse. Dress codes are casual throughout Costa Rica.
1 swimsuit cover-up or linen shirt: Serves as a sun layer, post-swim cover, and light shoulder coverage for meals near the beach.
Bottoms (pack 3-4)
1 pair of quick-dry hiking pants (convertible optional): For rainforest hikes, volcano tours, and cool evenings. Zip-off pants are legitimately useful in Costa Rica where a morning hike might go from 65°F to 85°F.
1 pair of shorts (quick-dry or nylon): For beaches and hot coastal days. Swim-trunk-style shorts that can handle water double as lake/river wear.
1 pair of longer walking shorts or lightweight pants: For town walking, dinner, and variable contexts.
1 pair of leggings (women) or joggers (men): For travel days, cooler nights at altitude, and evenings in Monteverde/Arenal where temperatures drop.
Skip: jeans. Too heavy, too slow-drying, and uncomfortable in humid heat.
Layers (pack 2-3)
1 lightweight rain jacket: Essential in rainy season, still recommended in dry season. Rainy season brings daily thunderstorms; dry season brings occasional evening showers, especially at elevation. See our best packable rain jackets guide.
1 light fleece or merino sweater: For cloud forest (Monteverde), Arenal evenings, and San José nights. Temperatures in Monteverde can drop into the 50s even in dry season.
1 lightweight long-sleeve (if not counted in tops): For wildlife tours that start before dawn and for evenings.
Underwear and socks
6-7 pairs of underwear: Quick-dry synthetic is the priority here. Merino holds up but dries slower in humidity. Hand-wash mid-trip; tropical humidity means slower dry times than elsewhere — plan for 12-18 hours to fully dry. See our best travel underwear (women) and best travel underwear (men) guides.
3-4 pairs of merino hiking socks: For hiking days. Merino wicks better than cotton and prevents blisters during long rainforest trails. See our best travel socks guide.
2-3 pairs of lightweight socks or no-shows: For town wear and beach days with sneakers.
Footwear
1 pair of hiking shoes or trail runners: Essential for most activities. Monteverde’s Cloud Forest, Arenal Volcano trails, Manuel Antonio’s park trails, and La Fortuna’s waterfall hikes all require proper footwear. Waterproof is a plus in rainy season but adds heat; breathable trail runners with quick-dry uppers are often the better choice.
1 pair of water-friendly sandals: Tevas, Chacos, or Keens. For river crossings, boat days, beach walks, and hot coastal afternoons.
1 pair of town/dinner shoes: Casual leather sneakers or slip-on loafers. Optional — many travelers skip this and wear sandals or hiking shoes everywhere.
Skip: flip-flops (fine for pool/beach but inadequate for town walking), heels (surfaces are often uneven), dress shoes (not needed).
Accessories
Wide-brim sun hat: UV index is often 11+ in tropical Costa Rica. A baseball cap does not protect the ears and neck. Packable UPF hats (Outdoor Research, Tilley) are worth the space.
Sunglasses with polarized lenses: For beach and water reflection.
Small daypack: For day tours, hikes, and beach carry.
Dry bag (5-15L): Surprisingly useful. River rafting, beach days with dry phones, unexpected rain. Small packable dry bags weigh under 2 oz.
Insect repellent (purchased locally or packed): Mosquitoes carry dengue and other diseases in Costa Rica; at-dusk hours require good repellent, especially in Caribbean coast areas.
Reef-safe sunscreen: Costa Rica has protected marine reserves where standard sunscreen is banned. Mineral sunscreen (zinc-oxide based) works best.
Reusable water bottle: Tap water is safe in most areas. Filter bottle useful for remote destinations.
Headlamp or small flashlight: Power outages are occasional in remote lodges, and night tours are a highlight of Costa Rica travel.
Quick-dry travel towel: For beach, hiking, waterfall swims. Microfiber packs small and dries fast.
Small first-aid kit: Costa Rica is well-equipped medically in cities, but remote locations (Monteverde, Osa Peninsula) are hours from pharmacies.
Pro Tips
Pack two of everything that might get wet
In rainy season especially, your hiking shoes, pants, and socks will get soaked during afternoon storms. Having a second set that is clean and dry the next morning is the difference between a great second day and a miserable one. This applies less in dry season but still matters for river and waterfall activities.
Cover the mosquito vector without overdressing
Long sleeves and pants at dusk reduce mosquito exposure significantly. Quick-dry fabrics are cooler than cotton for this coverage. Permethrin-treated clothing (can be purchased pre-treated or treated at home with spray-on permethrin) repels mosquitoes on contact and is effective for 5-6 washes. Worth considering for rainy season or Caribbean coast trips.
Be specific about which region you are visiting
“Packing for Costa Rica” is not one thing. A Nicoya Peninsula beach trip is different from a Monteverde cloud forest stay from a Tortuguero turtle-watching trip. The general list adapts — but add fleece for cloud forest, add extra swimwear for Pacific beaches, add waterproof duffel for multi-location transfers.
Rental gear is available for specific activities
You do not need to pack a surfboard, snorkel gear, or zip-line equipment. All three are abundantly available for rent or included in tours. This saves significant pack weight.
Consider a convertible packable bag for beach days
A packable tote that collapses to pocket size and expands to beach-bag size (Sea to Summit, Baggu) eliminates the need for a dedicated beach bag while still handling water-sport days.
What to skip
- Cotton anything (dries slowly in humidity, molds in tropical storage)
- Jeans (too heavy and hot)
- Dress clothes (Costa Rica is uniformly casual)
- Heavy hiking boots (trail runners handle most trails better in heat)
- Bulky camera gear (unless wildlife photography is the trip purpose)
- Hair tools (most lodges have limited electricity; humidity defeats styling)
- White clothes (red Costa Rican dirt stains permanently)
- High-end jewelry (petty theft risk in some areas; you will not wear it)
- More than one formal outfit (and often zero)
Regional notes
Pacific coast (Tamarindo, Manuel Antonio, Santa Teresa): Hot, humid, sunny. Heavy beach wear. Light clothing. UPF essential — see our UPF ratings guide for what those numbers actually mean. For beach-focused trips to these areas, our beach vacation packing list covers resort and swimwear essentials in detail.
Caribbean coast (Puerto Viejo, Tortuguero): Hotter, more humid, wetter. Mosquito protection essential. Similar beach wear but expect more rain.
Central Valley (San José, surrounding towns): Mild, moderate rain. Layered clothing. Less beach wear; more walking clothes.
Cloud forest (Monteverde, Santa Elena): Cool (55-70°F), wet, misty. Fleece and rain jacket essential. Closed-toe shoes. Expect daily mist even in dry season.
Volcano/Arenal: Variable — hot during day at lower elevation, cool at night. Layering essential. Rain jacket for hot spring walks.
Nicoya Peninsula / Guanacaste: Driest region. Hot and sunny even in rainy season. Heavy beach wear.
FAQ
Do I need quick-dry clothing in dry season, or is regular okay?
Quick-dry is still useful in dry season. Humidity stays high at beaches year-round, and even dry season has occasional showers. Cotton is still slower-drying than ideal. Quick-dry is not required but is more comfortable.
How much of a difference does rainy season make for packing?
Meaningful but not dramatic. Rainy season means: add a better rain jacket, pack an extra pair of shoes and socks, bring a dry bag, expect one wet day per two-three days. Dry season means: pack one rain jacket as a precaution, standard hiking gear, fewer backup items.
Can I get laundry done in Costa Rica?
Yes. Most lodges and beach-town guesthouses offer laundry service for $5-$15 per load. Turn- around is typically overnight. Humidity means clothes dried outdoors take longer; dryers are less common than in the US. Plan to do laundry once per week on a long trip.
What about clothes for zip-lining, rafting, or surfing?
For zip-lining: closed-toe shoes and long pants prevent harness chafe. Quick-dry is useful.
For rafting: swimsuit plus a quick-dry top. Water shoes (Tevas, water sandals) or old sneakers. Avoid anything you cannot afford to get soaked.
For surfing: board shorts for men, a rash guard and bikini or one-piece for women. Many surf lessons provide board and rash guard rental.
Is Costa Rica safe for traveling in athletic/sporty clothing?
Yes, generally. Costa Rica is casual throughout, and active/outdoor clothing is normal in most contexts. Avoid flashy jewelry and high-end gear displays in urban areas for safety, but technical hiking clothing and athleticwear are completely standard.
What about dressing for the Costa Rican culture?
Costa Rica is relaxed and beach-adjacent throughout. Dress casually, respect local customs at religious sites (long pants at churches), and dress slightly nicer for nicer restaurants (collared shirts for men, dresses or nice tops for women). No strict cultural dress codes.
Final thoughts
Costa Rica is one of the more packing-complex tropical destinations because of its climate variety. A good packing list handles the Pacific beach in the morning, the cloud forest in the afternoon, and the volcano lodge at night — without being twice as big as a single- climate tropical trip. The fabric choices matter more than usual: quick-dry throughout, layer with lightweight merino or fleece, waterproof outer shell at hand. With 15-18 pieces of clothing and two-to-three pairs of shoes, you can cover a two-week Costa Rica trip in a carry-on through most of the country’s varied ecosystems.
