Central Java Weather Forecast for Today, 6 March 2026: Potential Thunderstorms and Extreme Weather

Forecast for Central Java today, 6 March 2026, according to the Meteorology, Climatology and Geophysics Agency (BMKG), shows that extreme weather is likely to be widespread across 34 districts in Central Java on Friday, 6 March 2026. Thunderstorms and high waves persist at sea.

In Central Java, the morning is expected to be generally cloudy. Light to moderate rain is forecast to lash the eastern part of the North Coast of Central Java as it moves into the afternoon and evening, with rainfall intensities increasing and spreading more evenly across Central Java.

Rain and storms are also forecast in the northern and southern waters of Central Java, accompanied by waves of 1.25-2.5 metres, which remain ongoing. This poses risks to maritime activities such as fishing boats, barges, and freight or passenger transport when wind speeds exceed 15 knots.

‘Awas, bencana hidrometeorologi seperti tanah longsor, banjir dan angin puting beliung, kerana cuaca ekstrem berpotensi merata di 34 daerah di Jawa Tengah,’ said BMKG forecaster Ferry Oktarisa of the Ahmad Yani Semarang Meteorology Station on Friday (6 March 2026).

Adapun daerah-daerah di Jawa Tengah berpotensi cuaca ekstrem, Ferry Oktarisa listed Cilacap, Banyumas, Purbalingga, Banjarnegara, Wonosobo, Mungkid, Boyolali, Klaten, Karanganyar, Sragen, Grobogan, Blora, Rembang, Pati, Kudus, Jepara, Demak, Ungaran, Temanggung, Kendal, Batang, Kajen, Pemalang, Slawi, Brebes, Magelang, Surakarta, Salatiga, Semarang, Pekalongan, Tegal, Bumiayu, Majenang and Ambarawa.

Other areas will experience light to moderate rain, according to Ferry Oktarisa. Winds are from west to north at 10-30 km/h, temperatures range from 18-32°C, and humidity from 60-95%.

‘Warga di daerah perbukitan dan daerah aliran sungai diminta waspada,’ he added.

BMKG Maritime Station forecaster Sediyanto in Tanjung Emas Semarang said extreme weather, including thunderstorms with lightning, could also occur at seas around Central Java, with high waves persisting and posing risks to maritime activities. ‘Residents at sea, such as fishermen or visitors, should exercise caution due to these conditions,’ he urged.
