Culture
Maldivians are almost entirely Sunni Muslim, and the local culture is a mixture of South Indian, Sinhalese and Arab influences. While alcohol, pork, dogs and public observance of non-Muslim religions are banned on the inhabited islands, the resort islands are allowed to exist in a bubble where anything goes.
Note that the weekend in the Maldives runs from Friday to Saturday, during which banks, government offices and many shops are closed. You won't notice this at the resorts though, except that lunch hours may be shifted for Friday prayers.
Climate
The Maldives are tropical, with plenty of sunshine and temperatures around 30°C throughout the year. However, rainfall increases considerably during the April-October southwest monsoon, particularly from June to August.
