Saipan is one of the fastest growing tourist resorts in Micronesia with a huge amount of development in the past few years so if you want a more peaceful holiday, and see a more traditional side of the Mariana Islands, the smaller and less commercial islands of Tinian or Rota might be more suitable. All the islands have exceptional diving.
According to The Guinness Book of Records, Saipan has the world's most equable temperature, averaging 27°C (81°F) year-round. Humidity is always high but the even temperature and fresh sea breezes means conditions are never too stuffy. The rainy season is from July to October, when rainfall averages about 300mm (12in) a month and typhoons wreak havoc; from December to May the monthly rainfall average is only around 100mm (4in).
Bring new batteries for your torch, digital camera, dive computer etc as these kinds of batteries are difficult to find.

The Northern Mariana Islands are an archipelago made up by the summits of 15 volcanic mountains in the north-western Pacific Ocean.
Geographically, the Marianas are the northernmost islands of a larger island group called Micronesia. It consists of two groups, a northern group of ten volcanic main islands and a southern group. Only three of the islands, Saipan, Tinian and Rota, have a permanent population. Some of the islands that are unpopulated were evacuated as recently as 1990 due to the threat posed by volcanic activity.
The scuba diving around Saipan is excellent with the coral reefs and lagoon being home to a vast array of tropical fish. One of the best places for snorkelling is around Mañagaha, an old coral reef.
