Costa Rica Climate: Dry Season vs Rainy Season Packing
Costa Rica’s dry season runs from December through April, featuring average temperatures from 77°F/25°C in December to 82°F/28°C in April with rainfall under 50mm monthly, especially in Guanacaste and Manuel Antonio. Pack lightweight rain jackets and sun protection gear because sun exposure is intense and rain is rare but possible in afternoons.
The rainy season from May to November brings high humidity and heavy rainfall, peaking over 300mm in September and October in San José and Tortuguero.

Expect daily showers, so pack for moisture management.

Skip These: 7 Items That Waste Space in Costa Rica
Pack for the trip you are taking, not the trip you imagine; ditch these heavy or slow-drying items.
| Skip This | Why | Instead |
|---|---|---|
| Jeans | Jeans weigh around 900g and take over 18 hours to dry in Costa Rica’s 82% humidity, making them uncomfortable and impractical. | Two pairs of quick-dry nylon or polyester travel pants weigh about 300g combined and dry within 1 hour. |
| Full-size bath towel | Hotels provide towels, and full-size ones weigh 500g+ and take too long to dry in humid air. | A 150g microfiber travel towel dries fast and fits in your daypack for beach or hikes. |
| Cotton t-shirts | Cotton absorbs 7 times its weight in sweat and takes 3+ hours to dry, which is uncomfortable in Costa Rica’s tropical heat. | Pack 3-4 lightweight synthetic quick-dry shirts (weighing about 150g each) that dry in under 30 minutes. |
| Too many dressy outfits | Costa Rica’s nightlife and dining are casual; dressy clothes add unnecessary weight and rarely get worn. | One smart casual outfit with quick-dry fabric covers any upscale venue, weighing under 400g. |
| Laptop | Laptops add 1.3kg and bulk; most tasks can be done on smartphones, which are lighter and more versatile. | Use your phone for maps, bookings, photos, and communication to save weight and space. |
| Heavy hiking boots | Costa Rica’s trails are mostly humid and muddy; heavy boots (2+ lbs) take forever to dry and cause blisters. | Pack lightweight trail runners (around 1 lb) that dry quickly and provide sufficient grip. |
| Multiple bulky books | Books weigh 300-600g each and are redundant when phones and e-readers handle reading and navigation. | Download e-books or audiobooks on your phone, saving weight and space. |
| Full-size umbrella | Costa Rica gets sudden tropical showers, but full umbrellas are heavy and bulky to carry. | A compact, lightweight rain poncho (100g) fits in your daypack and covers you and your bag. |
