Lombok Barat (ANTARA) - The Meteorology, Climatology, and Geophysics\nAgency (BMKG) predicts that the rainy season in the West Nusa Tenggara\n(NTB) region will be delayed and shorter, lasting only about three to\nfour months.<\/p>\n
\u201cA normal rainy season lasts for six to seven months. However, this\nrainy season in NTB will be shorter, with a dominant duration of\napproximately 10-12 ten-day periods, or roughly three to four months,\u201d\nsaid the Head of the NTB Climatology Station, Nuga Putrantijo, during a\npress conference in Lombok Barat on Wednesday.<\/p>\n
The phenomenon of a longer-than-usual dry season is caused by a very\nstrong El Ni\u00f1o influence, monsoon circulation, and sea surface\ntemperatures around the waters of NTB, which affect the arrival and\nduration of the rainy season.<\/p>\n
The westerly winds, or the Asian Monsoon, are predicted to become\nactive in November 2026. Currently, the easterly wind circulation, or\nthe Australian Monsoon, at the 850mb layer still dominates the\nIndonesian region.<\/p>\n
Meanwhile, sea surface temperature anomalies in Indonesian waters\nfrom October 2026 to March 2026 are predicted to be dominated by normal\nto warm conditions, ranging between minus 0.5 to 1 degree Celsius.<\/p>\n
BMKG predicts the rainy season will begin entering the West Nusa\nTenggara region in December 2026. The peak of the rainy season is\nexpected to occur in March 2027, covering 14,168 square kilometres, or\napproximately 78 per cent of the NTB region.<\/p>\n
Nuga noted that the rainy season will also be wetter, as the amount\nof water that should be distributed over six months is instead expected\nto fall within a three to four-month window.<\/p>\n
He emphasised that water management planning and agricultural\nactivities are crucial in facing the rainy season.<\/p>\n
\u201cFor water resources and infrastructure, we need to anticipate water\nmanagement and drainage capacity. Regarding the disaster and\nenvironmental sectors, we all need to increase vigilance against the\npotential for puddles, floods, and landslides,\u201d said Nuga.<\/p>\n
The Regional Disaster Management Agency (BPBD) of NTB has advised the\npublic to take early mitigation steps in anticipation of the rainy\nseason, which is predicted to arrive in about two months.<\/p>\n
The Head of Rehabilitation, Reconstruction, and Disaster Management\nCooperation at BPBD NTB, Awan Darmawan, stated that the peak of the\nrainy season is prone to causing floods and landslides in East Lombok,\nWest Lombok, as well as the Sumbawa and Bima regions.<\/p>\n
He suggested that every household, particularly in the southern\nLombok area, should construct infiltration wells three metres deep with\na one-metre diameter to capture rainwater runoff.<\/p>\n
These infiltration wells are highly beneficial for storing water\nreserves while simultaneously reducing flood risks.<\/p>\n
\u201cThis is what we call rainwater harvesting\u2014storing water when it is\nabundant to be used when the dry season returns,\u201d said Awan.<\/p>\n
Furthermore, he directed village governments to utilise remaining\nvillage fund budgets for structural mitigation measures, including the\nconstruction of gabions, the repair of drainage systems, and the\ndredging of riverbanks to accommodate surging water volumes.<\/p>\n
Awan added that the primary proposals from legislative members are\nalso directed towards supporting disaster management efforts in West\nNusa Tenggara.<\/p>\n
\u201cDisaster management cannot rely solely on the BPBD. All elements of\nsociety must move together starting now so that we are not too late in\nfacing extreme weather,\u201d concluded Awan.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/bmkg-shortened-rainy-season-of-three-to-four-months-predicted-for-ntb-1790763416", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
