Costa Rica in October

Visiting Costa Rica in October is one of the country’s best-kept secrets. While it is the rainiest month in much of the Pacific, it’s also one of the quietest and most affordable times to travel. With fewer crowds, lower prices, and spectacularly lush scenery, October offers a truly unique experience. Even better, the Secluded Caribbean Itinerary is our top recommendation this time of year, guiding travelers to the drier Caribbean side with highlights like Puerto Viejo, Cahuita, Turrialba, and rafting along the Pacuare River. Some even extend their trip into Bocas del Toro, Panama, for an added adventure.

While the Southern Pacific—including the Osa Peninsula, Dominical, and Uvita—is best avoided due to heavy rains, the Caribbean shines with sunny skies and festive vibes. Arenal and Manuel Antonio can be a roll of the dice, but for those willing to take the chance, misty landscapes and fewer visitors can make the experience especially rewarding. October is a month where the rainforest feels alive, and the slower pace allows you to embrace Costa Rica more intimately.

What the Weather is like in Costa Rica in October

In October, Costa Rica splits into two very different climates. The Pacific side—stretching from San José to the west coast—is deep in rainy season, with showers almost daily, especially in the afternoons. In contrast, the Caribbean coast enjoys a refreshing mini-dry season. Towns such as Puerto Viejo and Cahuita thrive with sunshine and drier weather, so much so that high-season pricing can kick in early due to demand.

Rainfall

Rainfall levels vary across the country in October. Guanacaste (Northern Pacific) can see as much as 15 inches of rain and about 24 rainy days. San José averages 13 inches over 25 days, while the Central Pacific—including Quepos—receives around 12 inches across 26 days. On the other hand, Limón on the Caribbean coast averages only 7.5 inches of rain over about 15 days, making it noticeably sunnier than the rest of the country.

October on the Caribbean Coast

October is one of the best months to visit the Caribbean coast of Costa Rica. With its mini-dry season, this region becomes a hub for travelers seeking sunny skies, warm seas, and a lively Afro-Caribbean culture. Puerto Viejo and Cahuita are especially popular, offering everything from beach days to cultural immersion.

Temperature

Despite October rains, Costa Rica’s tropical warmth remains inviting. Coastal highs sit in the upper 80s to low 90s Fahrenheit (30–33°C), with lows in the mid-70s to low 80s (24–27°C). In higher elevations, like Monteverde or the Central Valley, daytime highs run between the mid-70s and low 80s (24–28°C), with cooler nights dipping into the 60s (15–20°C).

Wildlife and Activities

October is a dream month for wildlife lovers. The wetter Pacific coast draws out an abundance of animals, while the Caribbean offers excellent birdwatching and the chance to see the tail end of Tortuguero’s green sea turtle nesting season. On the Pacific, Parque Nacional Marino Las Baulas near Tamarindo is the place to witness endangered leatherback sea turtles nesting. Guided night tours make for unforgettable encounters under the stars.

Carnival / Carnaval (Early October)

After a brief hiatus, Carnival returned in 2023 and is anticipated again in 2024—so book your stay early.

Essentials include a lightweight umbrella, waterproof jacket, quick-dry clothing, and water-resistant shoes. For detailed guidance, see our Costa Rica Packing List.

Why Visit Costa Rica in October
