Tortuguero weather in June

Tortuguero forum threads describe August as a genuinely good month despite being deep in the rainy season - rain here tends to concentrate between 3-5pm and overnight, with Tortuguero getting noticeably less daytime rain than other parts of Costa Rica. Multiple posters, including a local, specifically recommended August for the turtle nesting season, which runs July through October, calling the rain a secondary consideration next to the wildlife draw. The general read: it's not the worst of the rainy season anywhere in the country, rains are usually brief and predictably timed rather than an all-day event, and the second half of August tends to run a bit drier than the first.

Forum posters describe Tortuguero as consistently hot and humid, not one of Costa Rica's cooler regions, and flag February specifically as a month where the Caribbean coast, where Tortuguero sits, is likely to run rainier and cloudier than the country's Pacific side even though February is broadly a good-weather month for Costa Rica overall. Posters are direct that February falls outside turtle nesting season, which runs July through October, but consistently still rate the destination as well worth visiting regardless - one visitor spotted a black river turtle and rated the wider wildlife-watching, birds included, as some of the best around. Posters generally recommend canal boat tours, canoeing or kayaking and a walk through the national park as year-round draws here, turtle season or not.
