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.
Tuvalu, the world's second-smallest country and, according to the United Nations, one of the least developed, fulfils the classic image of a South Sea paradise. Visitors come to the islands to enjoy the peaceful atmosphere and palm-fringed beaches. Pandanus, papaya, banana, breadfruit and coconut palms are typical. Traditional buildings with thatched roofs can be seen virtually everywhere on the islands.
The Constitution of Tuvalu states that it is "the supreme law of Tuvalu" and that "all other laws shall be interpreted and applied subject to this Constitution"; it sets out the Principles of the Bill of Rights and the Protection of the Fundamental Rights and Freedoms.
