Costa Rica 's very mild, Spring-like climate is ideal for travel year-round. Local conditions vary according to elevation, season and location. Expect average temperatures from 85-95 F and moderate humidity on the coast compared to cooler temperatures averaging 72 F in the mountains and Central Valley where you may need a light sweater at night. The peak travel period (Dec-Apr) and off-peak (May-Nov) generally coincide with Costa Rica's so-called'dry' and 'rainy' seasons. However, this is an inaccurate and simplistic description of climate and travel seasons. Costa Rica has more than a dozen climate zones which often contrast with each other; when rain falls in one region it tends to be drier in another. While the months of December through April tend to be almost rainless on the Pacific coast, this is when it rains the most on the Caribbean coast. On the other hand, the dry season on the Caribbean side is September and October, which is considered the so-called 'rainy season' in the rest of the country. Each year in July you can count on the annual veranito, or 'little summer' as the locals call it, when there is a predictable dry spell in the middle of the green season.
Most travelers visit Costa Rica to escape winter in North America when average rainfall throughout the country is low and migrant bird populations are highest. But others who prefer to travel during the off-peak 'green season' will appreciate natural areas more to themselves, lush vegetation, better choice of guides and accommodations, low season rates, greater variety of blooming orchids and flowers, and other benefits. During the green season rain usually falls for a few hours in the afternoon or at night and rarely disrupts travel, unless you are driving on secondary roads which can become impassable. It is impossible to predict climate for any specific place and time in the tropics. The increasing numbers of travelers visiting Costa Rica during the green season have made it a year round destination.

Costa Rica is home to over 9000 identified species of vascular plants, including over 900 different species of trees, and more are being described each year! From sub-alpine dwarf vegetation, rainforest flora from sea level to could forest to mangrove swamps and seasonal dry forest with its deciduous trees, there is an astounding range of floral habitats for a country so small. Costa Rica has roughly 1,500 species of orchids, almost all of them epiphytes. Costa Rica , in fact, provides much of the world's supply of orchids. Other epiphytes include bromeliads (over 200 species, much more commonly seen than the orchids.) The epiphytes, treetops and vines create a canopy that preserves the moisture within the forest, and also provides a home for many small animals and insects that live their whole lives in the canopy, never touching the ground. The cloud and rainforests of Costa Rica comprise some of the world's most complex ecosystems

Scarlet Macaw

Costa Rica is a favorite destination for many naturalists from all over the world, and its bird population is one of the main attractions. Over 850 species have been identified, far more than have been seen in North America, Europe or Australia ! These range from the resplendent quetzal, with its shimmering green plumage, scarlet belly, white tail feathers and green tail coverts that trail over 60 cm (2 ft) behind its body to the rare harpy eagle, which can snatch a monkey or a sloth right out of its branch in the treetops. There are over 50 species of hummingbirds, 15 parrots (including Scarlet Macaws), six toucan species, 75 different flycatchers, 45 tanagers, 29 ant birds and 19 cotingas.

Three-Toed Sloth	White-Faced Capuchin

Over 200 mammal species have been recorded in Costa Rica. Observant visitors to the national parks and other protected areas are almost certain to see one of the country's four types of monkeys -- howler, spider, white-faced capuchin and squirrel monkeys.
 
The country is also home to a wide assortment of other tropical mammals; two types of sloths, the often-viewed three-toed, a diurnal animal, and the rarely seen, nocturnal two-toed sloth. Three types of anteaters reside in Costa Rica; the tamandua is most commonly seen, while the others, the giant and silky anteaters are rarely glimpsed.






Butterflies, Insects & More

Blue Morpho

Over 35,000 species of insects have been recorded in Costa Rica, with thousands more still undiscovered. Most noteworthy among these are the butterflies. It is estimated that 10% of the world's butterfly species reside in Costa Rica

One of the most breathtaking is the blue morpho, with its 15 cm (6-inch) wingspan and electric blue upper wings. Floating over the rivers, usually on sunny mornings, they are a stunning sight. When they land, only their brown underwings are visible; a camouflage to protect them from their enemies. Such camouflage is prominent in the butterfly community. Some species look just like the leaves and bark of the trees on which they rest. Yet others have wings with spots that resemble eyes. Predators occasionally attack their wings, leaving them with only minor injuries, their heads and bodies safe from harm.

Basilisk	Green Tree Frog

Costa Rica is home to roughly 150 species of amphibians, some of which are extremely colorful and exotic. There are tree frogs which spend their entire lives above the forest floor, breeding in the water of tank bromeliads or in holes in the trunks of trees. Others, the poison-arrow frogs, are exuberantly colored, ranging from bright red with blue or green legs to bright green with black markings. These frogs emit skin toxins that are distasteful of lethal to their potential predators, and their bright coloration serves to warn predators of their danger.

There are over 200 species of reptiles in Costa Rica, over half of them snakes. But snakes are rarely encountered, even by those looking for them. Often they are nocturnal or superbly camouflaged, and if they lie perfectly still on the forest floor, they can be virtually impossible to detect. Much more frequently seen are the country's lizards. The common Ameiva has a white stripe running down its back. Bright green basilisk lizards can reach a meter (3 ft) in length. Their huge crests run the length of their heads, giving them the appearance of a dinosaur. They are nicknamed 'Jesus Christ lizards' because when they are young they can run across the water when disturbed. Costa Rica is also home to crocodiles and turtles. The 14 turtle species include both marine and freshwater varieties. The largest of the marine turtles are leatherbacks. Their shells are up to a meter and a half (5 feet) and they weigh upwards of 360 kg (800 lb)! Marine turtles climb up sandy beaches to lay their eggs, a spectacular sight because it happens en masse. Olive ridleys nest synchronously -- tens of thousands of females sometimes emerge from the sea in a single night!

Leatherback Turtle

Off the Pacific coast and around the offshore islands and coral reefs, snorkeling enthusiasts and scuba divers can find spectacular tropical fish, sea urchins, anemones and starfish.

This wildlife area is located on the pacific coast of Costa Rica, in the province of Puntarenas. Located 157 km south of San José and 7 km south of Quepos City. The park was created by Law No. 5100 on November 15, 1972. The park is comprised of 682.7 hectares land and 55.000 hectares of coastal waters Manuel Antonio National Park is a small biological island. Manuel Antonio is one of the most beautiful national parks in all of C.R.. Another important attribute are the humid tropical forests, where flora and wildlife species, endanger of extinction, may be found.

A geomorphic characteristic of the park is the Punta Catedral. In the past this was an island. Because of sediment accumulation it has joined to the continental mass, forming a sandy band called Tombolo. The park is located in a region of great precipitation and high peaks. The annual precipitation averages 3.875 mm. Summer months are January, February and March; and the winter months are August, September and October. Manuel Antonio National Park is located in the humid tropical forest zone.

Protected areas include primary forest, secondary forest, beach vegetation and sea environments. Species of flora that are most commonly found in the primary forest are Guácimo Colorado, Pilón, Cedro María, Guapinol, Guapinol Negro, the endangered Arbol Maderable, Lechoso, Madrono, Cenizaro and Ceiba. In the secondary forest, you may find balsa, peine de mico, guarumo, guácimo, capulín blanco and garocho. Manglar covers approximate 18 hectares, is constituted by three species: mangle colorado, botoncillo and mariquita. Amongst the beach vegetation, you will notice the manzanillo tree, the milk and fruit of which is extremely poisonous. Other species of trees found along the beaches are the almendro, the roble sabana and the coco tree. A plethora of wildlife may be found in the park. You can find 109 species of mammals and over 184 of birds here. Among the most import, are the Raccoon, Porcupine, Guatusa, 2-Finger Sloth, 3-Finger Sloth, Capuchin Monkey, Congo Monkey and the Squirrel Monkey, endanger of extinction from the destruction of their habitats and pet trade.
