Samoa is the heart of Polynesia with the To Sua Ocean Trench's swim hole on Upolu, the Le Pupu-Pue rainforest waterfalls, Robert Louis Stevenson's mountain home above Apia, and Falealupo's banyan tree canopy walk on Savai'i.
Trade-wind dry season with To Sua Trench swimming pleasant, surfing season at peak, and Teuila Festival in early September the country's main cultural event.
Teuila Festival in early September brings Samoan dance, fire-knife performance, and traditional fautasi long-boat races to Apia, the country's biggest event.
Wet season with afternoon storms, cyclone risk January-March, but Upolu's rainforest at peak greenery and Savai'i lava fields accessible between fronts.
Cooler dry-season window with surfing at Salani and Aganoa at peak swells, To Sua Trench at calmest, and Samoan villages running their faleaitu (theatre) shows.
