Central Java Weather Forecast 3 March 2026: Alert for 4-Metre Waves and Extreme Weather in 32 Districts
Indonesia’s Meteorology, Climatology and Geophysics Agency (BMKG) has issued an early warning regarding the weather forecast for Central Java on 3 March 2026. Waves reaching up to 4 metres are potentially occurring in southern waters and 2.5 metres in areas posing risks to shipping activities, with extreme weather conditions potentially intensifying across 32 districts in Central Java.
Morning weather in Central Java is reported to be generally cloudy with light rain in the Wonogiri region. As the day progresses into afternoon, evening and night, rain intensity increases with light to moderate rainfall distributed across Central Java, with extreme weather including heavy rain accompanied by strong winds and lightning strikes potentially affecting 33 districts, prompting residents to remain vigilant against hydrometeorological disasters.
Beyond thunderstorms, waves of 2.5-4 metres occur in southern waters and 1.25-2.5 metres in northern waters, posing risks to maritime activities particularly when wind speeds exceed 15 knots. Sea level rise (rob) continues to affect several districts in the North Coast of Central Java, resulting in flooding impacts.
“Maintain flood alert status for the North Coast of Central Java, as sea level rise with maximum heights of 1 metre continues in northern waters from 18:00-21:00 WIB,” stated Usman Effendi, forecaster at BMKG’s Tanjung Emas Maritime Station in Semarang, on Tuesday (3 March).
High waves accompanied by thunderstorms in southern and northern waters of Central Java, Effendi continued, pose risks to maritime activities including fishing vessels, barges and cargo and passenger transport, creating unsuitable conditions requiring serious attention.
Arif N, forecaster at BMKG’s Ahmad Yani Meteorological Station in Semarang, stated that weather conditions in Central Java had not improved by Tuesday (3 March), as extreme weather intensifies across 32 districts in both mountainous and highland areas, the Solo region, the North Coast, and western, central and southern Central Java.
Districts in Central Java with potential for extreme weather include Banyumas, Purbalingga, Banjarnegara, Kebumen, Purworejo, Wonosobo, Mungkid, Boyolali, Klaten, Sukoharjo, Wonogiri, Karanganyar, Sragen, Grobogan, Blora, Rembang, Pati, Kudus, Jepara, Ungaran, Temanggung, Kendal, Batang, Kajen, Pemalang, Slawi, Magelang, Salatiga, Pekalongan, Bumiayu, Majenang and Ambarawa.
“Residents are urged to remain vigilant against hydrometeorological disasters such as landslides, flooding and whirlwind gusts resulting from the potential extreme weather,” Arif stated.
Several other districts may experience light to moderate rainfall, according to Arif, with winds blowing from west to north at speeds of 10-30 kilometres per hour, air temperatures ranging from 18-32 degrees Celsius and air humidity ranging from 60-95 per cent.
