Things to Do in Costa Rica in October

October is picking season in the highlands above San José, the red cherries are ripe, the air smells like honey from processing, and the morning sun hits the volcanoes. You can hike between rows of coffee trees at 1,200 m (3,900 ft), fill a basket, then watch the same beans get pulped and dried. The altitude keeps temperatures at 21°C (70°F) when the coast is sweating.

Santa Teresa's beach break peaks in October, southwest season swells hit the point at Playa Carmen with real power, not the knee-high waves of April. Morning offshore winds groom the faces until 10 AM, then the onshore bump kicks up good for learning. Water stays at 27°C (81°F), so you can skip the wetsuit and surf until your arms give out.

October's mixed weather keeps the crowds away but the animals active, sloths drop lower when storms approach, white-faced capuchins forage in the almond trees along Playa Espadilla, and the howler monkeys howl more before weather changes. The park's main trail to Cathedral Point stays dry until afternoon, and you'll share it with maybe 20 people instead of 200.

October's cloud forest hits the sweet spot, enough rain to keep the moss glowing neon green. But not so much that trails turn to rivers. Night walks start at 6 PM when the forest wakes up: kinkajous crash through fig trees, tarantulas emerge from burrows, and the bioluminescent fungi glow brighter in the post-rain humidity. Temperature drops to 16°C (61°F) after dark, so you'll need that jacket you didn't pack for the beach.

October's afternoon storms herd everyone indoors, good for threading through the 120-year-old Mercado Central's maze of 200 stalls. The air hangs thick with coffee smoke and cilantro, vendors shout prices in rapid-fire Spanish, and you can taste three types of chicharrones before choosing which bag to buy. Rainy days mean longer conversations with the abuelas who've sold tamales since 1978.
