Also, keep in mind that most school in Costa Rica close for the month of July. There will be an increase in domestic tourism, so book early.

Packing for Nosara by Season

Year Round Essentials

• We suggest carrying your stuff in a large backpack instead of a suitcase if possible. The Osprey 55L is great if you are only bringing a carry-on (take the small bag part off for under your seat) and the Osprey 75L is our go-to for checking in a bag.
• Sun Bum Original SPF 50 Sunscreen: SPF 50 because the sun is powerful. We like Sun Bum because they are reef-safe.
• Teva Voya Flip Flops for men and for women: Waterproof and have a solid sole.
• Columbia Bora Bora Sun Hat: Slightly nerdy, but great for blocking the sun, folding up small in your luggage, and is made of breathable fabric.
• Sun Bum Cool Down Aloe Vera Lotion: Hopefully you don’t get sunburned, but if you do, this stuff is a lifesaver.
• Hero Microfiber Towel: Most hotels will have towels for showering, but not for the beach, Microfiber towels dry quickly and can easily fit in your luggage.
• Sun Bum Original SPF 50 Sunscreen: SPF 50 because the sun is powerful. We like Sun Bum because they are reef-safe.
• LifeStraw Go Water Filter Bottle: You can drink the water here, but it is safer to buy bottled water. We like LifeStraw to filter out any extra bacteria or impurities.
• Insect Repellent: Once the sun goes down the mosquitos come out in full force. It is worse during the rainy season, but you might experience them in the dry season as well.

Rainy Season Essentials

• The Anker Powerbox: A reliable battery pack to charge electronics if power goes out.
• Large Zip Lock Bags: Nothing ever dries in rainy season. Zip locks are great for seperating damp clothing in your luggage.
• Rain Jacket: I love the North Face Antora for women and the same jacket for men. Lightweight, breathable, efficient.
• Waterproof Backpack: We use ours year round because it is also great for the beach and boat trips, but especially good in rainy season for potentially wet adventures.
• Motion Sickness Pills: You might want these year round for navigating the crazy roads. However, they are especially helpful in teh rainy season if you plan to do a boat trip when waves can be bigger.
• Headlamp: Again, useful all year round since the sun sets by 6PM. Also great to have if the power goes out.

Safety Concerns by Season

• The sun is very powerful here. You really need to take sun protection seriously because it is so easy to get burned. I suggest wearing long sleeve swim shirts in the water, stay in the shade as much as possible, and wear SPF 50+.
• It is very easy to get dehydrated with the strong sun. Drink a lot of water and replenish your electrolytes when you can. Most stores sell Gatorade or Powerade, which I find really helps here.
• Because it is so hot you might find that you get worn out a lot quicker than you are used to on hikes and with other activities.
• During the rainy season, rip currents and big waves are more common. Be careful about where you are swimming and obey any posted signs.
• We suggest renting a 4×4 or at minimum an SUV with decent clearance for this area since some roads are unpaved. BOOK YOUR RENTAL CAR WITH 10% DISCOUNT

Our Opinion on Visiting Nosara

In recent years, Nosara has become such a popular destination. I find that it can be a little too crazy during the dry season because the infastructure just hasn’t caught up to demand.

For example, last year we were in Nosara in March. We went to the gas station and ended up waiting for over 30 minutes in line to fill up our gas tank.

I think May through July is a great time to visit Nosara. The waves are big for surfing, there are fewer tourists, and prices go down a bit.
