Central Java Weather Forecast 2 August 2026: Light Rain in 13 Areas, High Waves and Tidal Flooding
Light rain is likely to occur in 13 areas of Central Java on Sunday (2/8), while high waves of 1.25–2.5 metres and tidal flooding (rob) with heights of up to 0.8 metres persist in northern and southern waters, necessitating caution.
From morning to afternoon, weather in Central Java is generally expected to be sunny or partly cloudy. However, from late afternoon into early night, central and southern regions, particularly mountainous and highland areas, are prone to light rain, which may slightly lower the temperature. Risca Maulida, a forecaster at the BMable BMKG Ahmad Yani Meteorological Station in Semarang, noted that despite the ongoing dry season, uneven light rainfall may occur across several dozen areas in Central Java, providing some relief from the heat.
The areas identified for potential light rain include Purbalingga, Banjarnegara, Wonosobo, Boyolali, Karanganyar, Sragen, Ungaran, Temanggung, Batang, Kajen, Pemalang, Salatiga, and Ambarawa, while other regions are expected to remain sunny or partly cloudy throughout the day. Winds are predicted to blow from the east to the south at speeds of 5–35 km/h, with temperatures ranging between 16–34 degrees Celsius and humidity between 45–95 per cent.
In maritime conditions, high waves of 1.25–2.5 metres continue to pose risks to shipping activities. Wahyu Sri Mulyani, a forecaster at the BMKG Tanjung Emas Maritime Station in Semarang, warned of high waves in the southern waters from Cilacap to Purworejo, and in the northern waters covering western and eastern Karimunjawa, Jepara, and the Pati-Rembang area, particularly affecting fishing vessels and barges.
Furthermore, although tidal flooding (rob) has decreased compared to previous levels, it continues to affect the northern coast of Central Java. This has resulted in coastal flooding in several Pantura areas, including Pekalongan, Semarang, and Demak, which is proving difficult to recede. This tidal flooding is impacting local livelihoods, including transportation, port loading and unloading operations, inland aquaculture, and salt farming.
