BMKG: Beware of 2.5-Metre Waves in NTT Waters Until 19 February 2026
Coastal communities and maritime transport users should be alert to the potential for sea waves reaching 2.5 metres between 16 and 19 February 2026.
Kupang, NTT — The Meteorology, Climatology and Geophysics Agency (BMKG) has urged the public to be vigilant against potential waves of 1.25 to 2.5 metres across the waters of East Nusa Tenggara (NTT) from Monday (16 February) to Thursday (19 February).
“Coastal communities and maritime transport users should be alert to the potential for sea waves reaching 2.5 metres between 16 and 19 February 2026,” said Yandri Anderudson Tungga, Head of the Tenau Kupang Maritime Meteorological Station, in Kupang on Monday.
He said waves of up to 2.5 metres could occur in the southern part of the Sape Strait, the Flores-Lamakera Strait, waters south of Flores, waters south of Alor-Pantar, and the western and eastern sections of the Sumba Strait.
Waves of similar height could also develop in the Savu Sea, the Ombai Strait, waters south of Sumba, waters north of Sabu-Raijua, north-eastern waters, waters south of Sabu-Raijua, waters north of Kupang-Rote, the Pukuafu Strait, and waters south of Timor-Rote.
“Wind patterns across the NTT region are generally moving from the west-northwest at speeds ranging from 8 to 28 knots,” he said.
He added that such wind speeds have the potential to increase wave heights in a number of NTT maritime zones.
Accordingly, the BMKG has issued an early warning for high waves and potential strong winds effective from Monday (16 February) through to Thursday (19 February).
The BMKG also reminded fishing boat users to heighten their vigilance when sailing if wind speeds reach 15 knots and wave heights reach 1.25 metres. Meanwhile, barge operators should exercise caution when wind speeds reach 16 knots and wave heights reach 1.5 metres.
“The public, particularly those in coastal areas and maritime transport users, are urged to continue monitoring official and up-to-date information from the BMKG,” Yandri said.
