Costa Rica Weather in August

Although August falls within Costa Rica’s rainy season, surprisingly, you’ll often find more ideal weather than in the prior and following months.

What NOT to pack for Costa Rica

This is the section most travelers wish they had read first. Overpacking is the number one complaint we hear from guests on their first day. Less really is more when you are moving between regions.

Jeans: They never fully dry in the humidity. Swap them for quick-dry pants or shorts and thank yourself on day two.

High heels or dress shoes: You will not need them. Even nice restaurants in Costa Rica are casual. One pair of clean trail sandals does the job.

Too many shoes: Three pairs maximum: waterproof sandals, trail shoes, and flip flops. Shoes are heavy and take space.

Non-reef-safe sunscreen: It is prohibited in several reserves and harmful to marine ecosystems. Bring reef-safe from home. Brands like Raw Elements and Badger are good options.

A hair dryer: Almost every hotel and lodge provides one. Leave yours at home.

Valuables you cannot afford to lose: Leave the expensive jewelry and the laptop you need for work. Use your trip as a proper break.

Cotton everything:Cotton absorbs moisture and stays wet all day. Pack synthetics or merino for everything except maybe one casual outfit.

Practical tips for packing smart: documents, money, and tech

Your passport must be valid for the full duration of your trip.

Customs also requires a tiquete de salida proof of onward travel out of Costa Rica. This can be a return flight or a bus ticket to a neighboring country. Have it printed or easily accessible on your phone. See Costa Rica national park regulations via SINAC for entry requirements at protected areas.

Money

Colones (CRC) are the local currency; USD is widely accepted but change is given in colones
ATMs are available in most towns withdraw colones there rather than exchanging at the airport, where rates are poor
Visa and Mastercard accepted at most hotels, restaurants, and tour operators; carry some cash for small sodas and local markets

Health prep

Check the CDC health recommendations for Costa Rica before your trip they cover vaccines, repellent, and food safety guidance. Travel insurance is not required by law, but we strongly recommend it for anyone doing adventure activities.

Tech

Costa Rica runs on 110V/60Hz US travelers need no adapter or converter
Cell coverage is solid in tourist areas; download offline maps before heading into remote zones
WhatsApp is the primary communication tool in Costa Rica make sure it is installed and working

Do I need a visa to visit Costa Rica?

US, Canadian, and UK citizens do not need a visa to enter Costa Rica for stays up to 90 days. Your passport must be valid for the full duration of your trip. You will need to show a return or onward ticket at customs.

Is tap water safe to drink in Costa Rica?

Yes in most areas. Tap water in San José, Guanacaste, La Fortuna, and other major tourist regions is safe to drink and often tastes good. In very remote or rural communities, confirm locally before drinking. Carry a reusable bottle and refill with confidence in most places.

What is the best luggage for a Costa Rica trip?

A soft-sided rolling suitcase works well if you are staying in one or two places. If you are moving between regions beach, rainforest, and volcano a mid-size backpack (40–50L) is far more practical. It fits in small boats, shuttles, and keeps your hands free on trails. We see guests arrive with giant hard-shell suitcases and spend the trip wishing they had packed a bag.

Do I need to bring bug spray to Costa Rica?

Yes. We recommend a picaridin-based repellent like Sawyer 20% over DEET it works just as well in tropical conditions, does not damage gear or plastics, and has no harsh smell. Apply it especially at dawn and dusk during the rainy season.
