Understanding Costa Rica's Climate and Wildlife Seasons
Dry Season: December to April
The dry season represents the peak time for wildlife viewing in Costa Rica. During these months, animals concentrate around water sources, making them easier to spot and photograph.
Key advantages of dry season wildlife viewing:

Wildlife highlights during dry season:
- Scarlet macaws become more visible as they seek fruiting trees
- White-faced capuchin monkeys venture closer to lodges seeking water
- Crocodiles concentrate in shrinking rivers and lagoons
- Sea turtle nesting peaks on Pacific beaches (olive ridley and leatherback)

Frequently Asked Questions
What is the absolute best month for wildlife viewing in Costa Rica?
February and March consistently rank as the optimal months for wildlife viewing, combining dry weather, peak animal activity, and excellent accessibility to remote locations. However, the "best" month depends on your specific wildlife interests and target species.
Is wildlife viewing better during dry season or green season?
Dry season (December-April) offers easier wildlife spotting due to animal concentration around water sources and reduced vegetation. Green season (May-November) provides unique opportunities like bird migration, amphibian activity, and baby animals, though with more challenging weather conditions.
How far in advance should I book wildlife tours?
Book 3-6 months in advance for dry season travel, especially for premium eco-lodges and specialized wildlife experiences. Green season bookings can often be made 1-3 months ahead, though popular destinations still benefit from early planning.
What wildlife can I expect to see year-round?
Costa Rica's resident species include sloths, howler monkeys, iguanas, crocodiles, and hundreds of bird species that remain active throughout the year. Seasonal variations affect visibility and behavior rather than presence.
Are there wildlife viewing opportunities during the rainy season?
Absolutely! Green season offers exceptional wildlife experiences including peak bird migration, maximum amphibian activity, incredible insect diversity, and the emergence of baby animals. Many experienced wildlife enthusiasts prefer this season for its unique opportunities.
Which coast is better for wildlife viewing?
Both coasts offer exceptional wildlife experiences with different specialties. The Pacific coast excels for marine wildlife, dry forest species, and accessibility. The Caribbean coast features different ecosystems, green turtle nesting, and unique species like poison dart frogs.
