From howler monkeys to toucans, the dry break draws out more than just tourists.
What is Costa Rica’s “mini summer”?
Mini summer, or “veranillo de San Juan”, is a brief dry spell that usually occurs between late June and mid-July, interrupting the otherwise rainy season. This phenomenon mostly affects the Pacific side of the country, including Guanacaste, Puntarenas, and parts of the Central Valley. It’s like a surprise encore of the dry season, complete with sunny skies, lower humidity, and a noticeable change in how animals move through their environment. During this short seasonal break, wildlife becomes more active and easier to observe. Trails dry up, vegetation thins slightly, and visibility improves. Tourists who come during this time often get the best of both worlds: the lushness of the rainy season without the heavy daily downpours, and some of Costa Rica’s most iconic animals putting on a show.
Why is wildlife more visible during the mini summer?
Animals are more visible during mini summer because they’re drawn to newly exposed food and water sources, and the drier conditions make them easier to spot. With less rain falling, animals tend to gather around rivers, ponds, and shaded trails. At the same time, with lower foliage density, visitors get clearer views into the jungle canopy and underbrush.
- Howler monkeys – These loud, leaf-loving primates often gather in troops in the treetops, and during the mini summer, their deep guttural howls can be heard echoing through the forests at dawn and dusk. They tend to be more active during cooler mornings when food is plentiful and easier to reach.
- Sloths – Usually reclusive and slow-moving, sloths are easier to spot when they descend from the trees for their rare bathroom trips, sometimes timed with the more predictable dry spells. With less rain and mud, they’re also less camouflaged and more exposed, especially near cecropia trees.
- Toucans and parrots – These flamboyant flyers thrive on seasonal fruits. With trees producing more visible, ripe fruit during the dry season, toucans (especially the keel-billed kind) and squawking parrots can be seen and heard across Costa Rica’s national parks and even in rural backyards.
- Coatis – These raccoon-like mammals love foraging near human paths. They often come in groups called “bands,” snuffling along the forest floor for fallen fruit and insects. Drier paths and clearer trails during mini summer make them easier to observe, especially in national parks and reserves.
- Crocodiles and iguanas – As the sun returns, these cold-blooded reptiles use the dry spell to regulate their body temperatures. You’ll often spot them lounging openly on riverbanks, roadside ditches, and sandy patches, especially in Guanacaste and along the Tarcoles River.
Where are the best places to spot wildlife during this season?
Costa Rica’s national parks become even more rewarding during mini summer, as animals come out to bask, forage, and socialise in the warmth. The drier trails also make it easier for travellers to explore deeper into reserves without needing heavy rain gear or enduring muddy paths.
- Manuel Antonio National Park – Known for its white-sand beaches and compact trail network, this park is packed with wildlife. During mini summer, the monkeys are bolder, sloths are more visible in the coastal almond trees, and iguanas practically pose for pictures.
- Corcovado National Park – Often called the most biodiverse place on Earth, Corcovado becomes slightly more accessible in the dry window. You might glimpse tapirs wallowing in forest pools, troops of squirrel monkeys in the trees, or even the elusive jaguar tracks near riverbeds.
- Rincón de la Vieja – This volcanic park in Guanacaste offers hot springs, bubbling mud pits, and plenty of wildlife, including spider monkeys and colourful birds. Mini summer makes hiking its geothermal trails easier and far more enjoyable.
- Monteverde Cloud Forest Reserve – With slightly less rainfall during mini summer, the misty forest trails of Monteverde open up. You might catch the resplendent quetzal displaying its emerald feathers or spot tree frogs emerging from mossy hideouts.
- Tamarindo Estuary (Las Baulas National Park) – This mangrove-filled estuary bursts with birdlife and reptiles during mini summer. Boat tours become smoother, and spotting howlers, herons, and crocodiles becomes a near guarantee.
What’s special about birdwatching during this time?
Birdwatching hits a sweet spot during the mini summer, when the clearer skies and seasonal fruiting patterns draw birds out into the open. Many birds are either actively breeding or migrating through, creating a soundtrack of calls and songs across the forest canopy.
- Keel-billed toucans – Their comical rainbow beaks and loud calls make them easy to spot and identify. They often perch high in trees, feeding on berries and showing off to potential mates.
- Motmots – These tail-swinging beauties are shy, but easier to spot in the filtered light of mini summer mornings. Their signature blue-green plumage and distinctive tail feathers are a treat for birders.
- Tanagers and manakins – With electric colours from red and orange to sapphire blue, these small birds flit through the mid-canopy. Males often perform elaborate dances and calls to attract mates.
- Parakeets and parrots – These social birds love to chatter in the treetops and are commonly seen in flocks. Look for them near fruiting palms or flying overhead near dawn and dusk.
Are reptiles and amphibians also more active?
Reptiles love the warmth, and amphibians find their moments when the humidity spikes—even during mini summer. The combination of occasional light showers and sunny spells creates micro-habitats where both groups thrive.
- Green iguanas – Often basking in the sun on tree branches, rocks, or fenceposts, these prehistoric-looking reptiles are easier to spot as they warm up. Some reach over five feet in length.
- Jesus lizards (basilisks) – These fast runners are famous for sprinting across water. You’ll often see them sunning on riverbanks before dashing into the water to escape.
- Cane toads and red-eyed tree frogs – These amphibians appear during early morning hours or after light rain. Tree frogs, in particular, are a favourite of photographers due to their vibrant colours and dramatic poses.
- Snakes – You might spot a non-venomous vine snake dangling from low branches or a boa constrictor curled near a sunny patch. Though sightings are rare, they tend to be more visible on clear, warm days.
Does mini summer affect insect life?
Yes, and it’s a brilliant time to see pollinators in action. Butterflies, bees, and dragonflies are everywhere, adding colour and energy to the dry season. The sudden bloom of flowering plants means insects are buzzing from blossom to blossom.
- Blue morpho butterflies – These large, metallic-blue butterflies seem to shimmer through sunbeams. They love flying near trails, rivers, and open forest areas.
- Stingless bees – Native to Costa Rica, these bees play an important role in pollinating rainforest plants and are often found near flowering trees and medicinal gardens.
- Leafcutter ants – These tireless workers form long lines, carrying pieces of leaves back to underground fungus farms. They’re especially easy to spot on dry trails, forming living highways across the forest floor.
What should you pack for a wildlife-spotting adventure?
Comfort, preparedness, and a good set of eyes are key to making the most of your mini summer wildlife adventure. This isn’t the time to overpack, but a few key items can make all the difference between a good day and an unforgettable one.
- Binoculars and a camera with zoom – Animals don’t always come close. A good zoom lets you appreciate birds and monkeys from a distance without disturbing them.
- Refillable water bottle – The heat ramps up fast, so hydration is essential. Many parks don’t have water stations, so come prepared.
- Reef-safe sunscreen and natural insect repellent – Protect yourself without harming the environment. Look for DEET-free options and biodegradable formulas.
- Quick-dry clothing and a light rain jacket – Even during mini summer, a quick shower can sneak up. Lightweight fabrics help regulate your temperature.
- Sturdy hiking shoes or sandals with grip – Wet roots, loose rocks, and slippery leaves are part of the experience. Good footwear prevents slips and sore feet.
