Travellers are recommended to take out full medical insurance before departure. Tuvalu's only hospital is in Funafuti; the outer islands only have trained nurses. More serious and complicated problems may require medicinal evacuation to Fiji or Australia.
Tuvalu experiences westerly gales and heavy rain from October to March, the period that is known as Tau-o-lalo, with tropical temperatures moderated by easterly winds from April to November.
The Islands of Tuvalu consist of six atolls and reef islands. The smallest, Niulakita, was uninhabited until it was settled by people from Niutao in 1949.
