JAKARTA - The Yogyakarta BMKG predicts that the potential impact of the rob which is predicted to occur along the southern coast of Yogyakarta from June 14 to 23, 2022, will not have an impact like what happened on the North Coast (Pantura) of Java.

"Because our land is higher than sea level, the rob that occurred in the south of DIY is different from what happened in northern Central Java," said the Head of the Yogyakarta BMKG Forecasting Data Analysis Group Romadi when confirmed in Yogyakarta, Tuesday, June 14.

The impact of the tidal wave on the southern coast of Yogyakarta will have a range that varies according to the altitude of the land.

"If it's like in Samas Beach, it's shorter, maybe the reach will be further," he said.

Although it has the potential to trigger abrasion or damage along the coastline, he ensures that the tidal wave does not reach residential areas.

"In this DIY, between sea level and land, thank God, the land is higher, so the rob will not reach settlements," he said.

He also asked people who are active along the south coast, especially tourists and fishermen, to increase their awareness of the impact of the tidal wave.

"As we approach this holiday season, we hope that tourists avoid bathing on the beach, then fishermen using outboard boats should be careful by monitoring information from the BMKG," he said.

Romadi said that the tidal wave is predicted to occur due to the influence of the supermoon phenomenon, namely the full moon phase which coincides with the phase of the highest tides.

The closest distance from the Moon to the Earth will occur on June 14, 2022. At this closest distance, the wave height on the southern coast of DIY is estimated to reach more than 2.5 to four meters.

The high waves were also triggered by the emergence of low pressure patterns in western Australia, southwest Sumatra, and southwest Kalimantan.

"This low pressure pattern forms a consistent wind speed pattern with speeds that can reach 45 km per hour and even more, this fast speed pattern also affects the wave height which is quite high," he said.

The Yogyakarta BMKG has issued an early warning of high waves on the southern coast of DIY which is valid from 13 to 23 June 2022.

"The potential for high waves is almost all over Indonesia," he said.
