Bali, the Gilis are somewhat sheltered and actually enjoy a slightly drier microclimate when compared to the surrounding archipelago. Dry Season usually lasts from May until October, with monsoon season starting in November and continuing through to April. Temperatures range between 22 °C to 34 °C, with an average annual temperature of around 28 °C. History Due to their small size and population, and relatively recent settlement of the islands, published sources are limited. Where local knowledge has been used, those cited are elected local officials whose details are listed in the references section. For more detailed regional historical information, visit the Lombok article. For a brief period during the Second World War, occupying Japanese forces used the islands as a lookout post and prisoner of war camp. Relics from this period include the remains of a bunker on the hill of Gili Trawangan, and the wreck of a patrol boat submerged at a depth of 45 m in the bay to the south of Gili Air (now a popular dive site). Permanent settlement only began in the 1970s, mainly due to the lack of fresh water sources before that time. Prior to human settlement, these islands remained pristine wildlife mangrove habitats. Initially, Bugis fishermen used the islands as a stop off location for their voyages around the archipelago. In 1971 the governor of Lombok, Wasita Kusama, began to establish coconut plantations and gave land rights to private companies. Some 350 inmates from the overcrowded prison in Lombok’s largest city Mataram, were sent to help with the first harvests between 1974 and 1979; many of the inmates remained on the islands as permanent settlers. Following various difficulties with coconut harvests, the private efforts to exploit the islands' plantations were abandoned. The local population grew beyond their allocated bounds (100 hectares) and began to erect homes and businesses on the private, abandoned land. This led to a land dispute that continues to the present. In the 1980s, the islands started to be discovered by backpacker tourists. This was influenced by the exponential rise of tourism in neighbouring Bali. At first, Gili Air (having the most infrastructure at the time) began to transform to cater to this new economy. However, Gili Trawangan soon surpassed it, due mostly to its proximity to better dive locations. As the prospects for tourism on the islands began to rise in the late 1980s and early ‘90s,
