Weather is Perfect in Costa Rica Because Microclimates

What is a microclimate?

There are five main global climate categories including tropical, dry, temperate, continental, and polar. Environmental factors like altitude, atmospheric pressure, wind patterns, location, and geographical characteristics like mountains and bodies of water all influence climate.

Every place on earth has a climate unique to its location, but some places are fortunate enough to claim a set of atmospheric conditions that are not the same as areas nearby. These conditions create a microclimate.

Microclimates can be as small as several square feet or as large as many square miles. The factors that influence a microclimate include moisture, temperature, atmospheric winds, vegetation, soil, latitude, elevation, and season. For example, wet soil promotes evaporation and increases humidity in the air.

Are microclimates everywhere?

You may be familiar with microclimates in your own location. For example, people who live in the mountains can tell you about the shift in temperature between the valley and higher on the mountain. In ski towns, this is called inversion. Inversion means that the temperature change due to altitude increase is reversed.

Hawaii is known for its microclimates. On Maui, you find warm and dry beaches on the southern side of the island and lush tropical jungle created by more regular rainfall on the north side. In fact, if you head up in elevation you can find strawberry farms and pine forests.

You may think you know an area’s climate pretty well, but perhaps you hadn’t considered its microclimates.

How many are there in Costa Rica?

Costa Rica is between the Pacific and Caribbean Oceans, approximately ten degrees from the equator, in the tropics. Here we experience wet and dry seasons rather than the four seasons of more temperate zones, summer, fall, winter, and spring. The wet season is May to November, and the dry season is December to April.

So even though Costa Rica is tropical, there are several microclimates within the country, each with a unique effect on the landscape and temperature.

Central valley

The central valley has a more temperate climate because of altitude and its proximity to surrounding mountains. The temperature is cooler and the growing season is all year. Low temperatures here average 62 degrees (F).

This central valley includes the large capital city of San Jose and its far-reaching suburban areas like Alajuela, Heredia, and Escazu. The city of Cartago is also in this region. Many people choose this location to live because they see it as having an endless spring.


The Caribbean is warm and moist as it experiences heavier rainfall and is affected by tropical depressions and storms. Despite this, even when it downpours, you will still likely see the sunshine for some of the days.

Here you will find the Tortuguero rainforest that dominates the northern landscape, surfing beaches, the reefs of Cahuita National Park, the busy port of Limon, and Puerto Viejo in the south close to the border with Panama.

Southern Pacific

The southern Pacific is like the Caribbean in terms of rainfall amounts, and thus it remains lush all year round. This area includes the Osa peninsula and the national park of Corcovado both of which are full of a variety of wildlife and jungle growth.

This area includes gloriously remote Drake Bay, Puerto Jimenez, and Golfito. Though this region experiences a wet and dry season, the annual rainfall here averages 162 inches.

Northern Pacific

Guanacaste, in the northern Pacific zone, is much drier than any other place in the country. Most people think of Costa Rica as a green jungle, but this region can look more like an African savannah during the dry season. The air is dry, and the dust is constant from December to April.

The beaches of this region are popular and beautiful, but you can’t miss the extraordinary farms nestled into the area’s foothills where ranchers and cowboys work the herds and the land.

Mountains near the central valley

The mountains surrounding the central valley have their own unique microclimate and are the coolest location in the country, but the humidity remains high and can generate a beautiful mist in this zone.

Here you will find excellent growing weather perfect for gardening and raising fruits and vegetables. The colder temperatures make for delightful evenings.

Which microclimate is the best?

There is no such thing. Each climate zone has unique characteristics and traits, and often you can find microclimates within microclimates. Think of it this way: if you live on a high mountain, temperature and moisture will impact your weather, but you will also experience the effects of wind.

You need to ask yourself what you want from your new home in terms of climate and weather. If you love to have a garden and grow beautiful hydrangeas, you will want to be in a zone conducive to that kind of growth. You might look for property in Arenal or Monteverde or even the central valley closer to the capital city of San Jose. The cooler temperature and dependable rainfall will be ideal.

If you want to have endless beach days, definitely look into Guanacaste but don’t expect to grow a garden there without a serious irrigation system because the dry season is dry and devoid of a drop of rain for months at a time.

Costa Rica offers tremendous depth in climate experiences, and you can explore all the different areas. First, define what brings you joy and your expectations, and then take time to discover your favorite spot.

Life in a tropical zone with microclimates

One of the most amazing things about Costa Rica is the natural environment. Living here affords you multiple opportunities to explore the rich tapestry created by interwoven climate zones and microclimates.

In one day you can careen through lush rainforest on a high zipline, float in a volcanic mud bath, and cruise on a horse through dry trails and beautiful sand beaches. Take some time to examine the different areas of the country and note the topography, the things that grow there, and the colors of the landscape.

Each area is so different from another that you can spend years wandering and discovering unknown places and still miss things. Take advantage of the extensive national park system, which has experts and knowledge to share relative to every location. These folks dedicate their lives to understanding the flora and fauna of any region and are happy to impart their wisdom. Ask questions.

The good news is that having so many microclimates means that there is something for everyone. Whether you enjoy lush coastal areas teeming with wildlife like the Osa Peninsula or higher elevations with cooler nights, you will find it in Costa Rica.
