Samoa is very religious, with the majority of the people belonging to the Anglican Church. This implies that Sunday is usually observed as a holy day, with the majority of stores and enterprises closed. On Sundays, you should not go for a stroll around the villages.
At sunset, several communities impose a prayer curfew. This usually lasts around 30 minutes. To prevent offending anybody, you should avoid going through villages at this time.
Samoan culture follows rigorous rules and decorum. Although exceptions are allowed for outsiders, it is prudent to avoid wearing exposing clothes and to follow local regulations, which are enforced by village matai (chiefs), albeit Apia is fairly flexible in these customs.
Topless women are frowned upon, and they should only wear swimsuits to the beach. Knee-length shorts are recommended. When not at the beach, shirts should be worn. A lavalava (sarong) is almost always appropriate clothing.
Other basic rules should be followed, such as removing shoes before entering a home (or, for that matter, a cheap hotel).
The major island of Upolu is regarded as the “modern” island, with most northern shore villages loosened with old rigid customs, while Savai’i is the most traditional island, although has grown more relaxed. However, naked bathing is strictly prohibited.
