Costa Rica is a particularly small country with one of the largest ranges of climates and climate zones in the entire world. While this can make packing for your vacation an extra challenge, it also means that you’ll be able to take a beach vacation complete with rainforest adventures, chilly mountain hikes, and volcanic views all within a couple days. In fact, if you take a simple drive from Atenas to Cartago, you might pass through 3 distinct climates in just over 3 hours. You’ll start in the sweltering Atenas heat, move to the crisp Central Valley air, and finally end up in rainy, cold Cartago. Currently, scientists are debating the exact number of climate zones in Costa Rica, as there are many ways to measure such areas. Using a variety of factors such as elevation, rainfall, and topography, local scientists are observing around 12 climate zones and possibly thousands of microclimates. Costa Rica, having such fertile soil and around 4% of the world’s total biodiversity, creates a situation where microclimates can be close together and wildly dissimilar. Climbing a steep volcano, for example, you’ll notice the variety of thrush plants and wildlife changing as you ascend, creating multiple ecosystems. Whether you are visiting Costa Rica for a quick vacation or planning a long-term move, you’ll want to be familiar with these climates before settling on a destination. This will help you make the most of your time in this rich and diverse land and may make packing for your trip just a little bit easier.
Rainforests are a major draw to Costa Rica for visitors as they offer some of the most amazing biodiversity imaginable. These forests dominate the southwest corner of Costa Rica as well as Atlantic lowlands, with their iconic towering trees and swooping vines. The Costa Rican rainforests are usually extremely dense and humid, and only very few parts can actually be hiked and explored. A defining characteristic of a rainforest is the dense canopy of trees towering above you. In the thickest parts of the forest, this canopy will block out light completely to the lower layers, meaning the ground can be home to only nocturnal animals and the toughest of plant life. In areas where the light breaks through, the undergrowth will be thick and fertile, and an incredible amount of wildlife and tropical plants will be easily observed.
As the name suggests, these areas receive a significant amount of rain year-round. The weather will be hot and humid and regardless of the time of year, some parts will be covered in a thick fog. This is one of the most important and productive ecosystems in the world, as it fights the negative effects of greenhouse gases while offering a suitable habitat for rare animals, including mammals, fish, insects, reptiles, amphibians, and birds.
When you move into high elevation areas, including the slopes of volcanoes or the peaks of the mountains, you’ll have no questions as to why the area is called a cloud forest. Towering above the natural cloud line, these zones are characterized by a thick fog and a dense growth of moss and fern. If you’re able to climb above the fog, you’ll be able to look down upon the cloud line on what feels like a totally isolated peak, with no view of the lands below. These areas will be chilly and rainy, but will be well worth the cold as you’ll observe plants and animals you most likely have never seen before. As you ascend or descend the slopes of the cloud forests, you’ll notice the change of temperature and ecosystems during the crossings of microclimates.
This is absolutely the best climate zone for ziplining, or canopy tours. In a light jacket and water-proof hiking boots, you’ll be able to see some of the most incredible forest views. If you find the right tour, you may be able to zip past a couple of different climate zones, noticing the change in growth and temperature as you descend. While this may not be the tropical getaway many Costa Rica vacationers are looking for, it is absolutely worthy of a couple days in your itinerary.
Tropical Dry Forests
The Tropical Dry Forests are the third and final type of forests in Costa Rica, according to the majority of local scientists and geographers. These forests will occupy the lowlands and valley areas, receiving significantly less rain than the two previous forest types. Regardless of seldom rain, tropical dry forests still offer the biodiversity you’re looking for in terms of tropical flowers and trees.
The Tropical Dry Forest occupies a significant part of Costa Rica’s overall land mass. This area is usually deciduous with broad-leaf trees. As this forest type most usually occurs in flat lands, these are also the areas most in danger of being cut down for commercial lumber or to create farms and ranches. The climate in the tropical dry forests can be most iconic of Costa Rica, as it experiences 6 months of dry weather, followed by 6 months of rain. Although the temperature may not be as sweltering as it is near the beaches, you’ll never deal with a frigid night either. The rain pattern in this area means that the landscape changes drastically thought the year, opposed to the other forests which may not alter much through the seasons. If you visit the Central Valley specifically for the Tropical Dry Forests, you may want to time your trip to be after a couple months of rain, so the landscape is green and thriving again.
Many people use the word “jungle” interchangeably with “rainforest,” but this is not quite the truth. The rainforest is characterized by long, thin trees creating a canopy so dense that sunlight is blocked from the ground below. Where the trees break and sunlight comes through, the ground layer grows thick and fertile plant life, fostering animal and insect diversity in incredible proportions; these are your jungles. Jungles often occur on the outskirts of rainforests or where the rainforest has experienced a natural disaster, like a fire or tree damage from an earthquake. A jungle has thick undergrowth and provides natural habitats to many types of animals, from those who live ground-level to those which stay in the trees, even bird species who nest above the canopy. These areas can be more difficult to navigate as the undergrowth and naturally occurring mangroves are obstacles to a hiker, but those who dare to make the journey will have the experience of a lifetime.
As Costa Rica is home to many types of forests, there are many different types of jungles. Some adventurers might seek out a well-maintained, guided hike focusing on tropical flowers and birds, while others may venture into the more forested part of the jungle, needing to rely on difficult trails and kayaks to reach their goal. Fortunately for the visitors to Costa Rica, you’ll most likely find both options within a couple hours’ drive of where you are planning to stay.
The tropical beaches of Costa Rica are probably the reason for your trip. With nearly 800 miles of coastline, bordering both the Pacific Ocean and the Caribbean Sea, Costa Rica offers the best of tropical vacations. These beaches range from white sand shores to blackened volcanic sand, but will offer hot weather and crisp, clean waves regardless.
The tropical beaches of Costa Rica can include various microclimates, depending on which coast you choose to visit and where on the coast you stay. Regardless of the area, you can generally plan for 6 months of dry weather followed by 6 months of rain. You can also plan for hot temperatures, humid air, and very direct sunlight. This is the area where you are most likely to enjoy a cold beer in a hammock and enjoy the tropical culture, so make sure you pack sunscreen and drink plenty of water.
Both the northern and the southern areas of Costa Rica have mountain ranges, and many beautiful mountain towns have popped up. The mountains are a perfect example of the country’s biodiversity, as microclimates change rapidly as you ascend or descend the range. Generally speaking, the higher you go, the colder it is. While some people move to the peaks of mountains to take advantage of the cold air and perfect views, some of the most popular Costa Rican towns will be found in the mid-range. In these areas, the weather can stay between 70 and 85 degrees year-round, with a host of diverse flora and fauna. You’ll have easy access to cloud forests, cities in the Central Valley, and beaches within a couple hours’ drive. Costa Rica may be famous for its beaches, but there’s good reason that so many people are moving to mountain towns boasting the best climate in the world.
Volcanic land is a microclimate of its own, as after an eruption the area will be covered in a nutrient-dense ash. While this ash has its place in the creation of new ecosystems, dormant or less-active volcanoes will be host to any number of the other climate zones. Volcanoes can peak up around rainforests, offering forested hikes, waterfalls, streams, hot springs, and a significant variety of plant and animal life. This is another climate zone in which the microclimates shift as the altitude changes. While very few communities will live on the base of active volcanoes, Costa Rica has around 200 volcanic formations over the entire country, most dead or dormant. This offers the perfect opportunity to hike, zipline, or horseback your way through a new ecosystem and climate zone.
