Central Java Weather Forecast for Sunday, 19 July 2026: Light Rain in 5 Regions
Light rain is likely to fall in five areas of Central Java on Sunday (19/7), while warnings remain in place for high waves reaching 2.5 metres and tidal flooding (rob) in the northern and southern waters, which will disrupt residents’ activities.
The weather across most of Central Java on Sunday (19/7) is expected to be partly cloudy and cloudy throughout the day. However, five mountainous and highland regions have the potential to experience light rain from the afternoon until early evening, namely Purbalingga, Banjarnegara, Wonosobo, Kajen and Pemalang.
The Meteorology, Climatology and Geophysics Agency (BMKG) reiterated its warning about forest and land fires (Karhutla) due to the current dry season. The absence of rain for months has caused plants, trees, twigs and leaves to become dry and highly flammable, even from the smallest spark.
“Apart from Karhutla, also be aware of health conditions due to the current weather changes, as rapid temperature shifts can affect the body,” said Winda Ratri, a forecaster at the BMKG Ahmad Yani Meteorological Station in Semarang, on Sunday (19/7).
According to Winda Ratri, the uneven chance of light rain, particularly in mountainous and highland areas, is enough to make the dry season conditions in those regions warmer. However, residents should remain alert to wind speeds blowing from the east to the south at 5-35 kilometres per hour, air temperatures ranging from 16-33 degrees Celsius, and humidity levels of 45-95 per cent.
Meanwhile, high waves of 1.25-2.5 metres in the northern and southern waters continue to pose a significant risk to shipping activities, including fishing boats, barges, and cargo and passenger vessels, especially when wind speeds exceed 15 knots while sailing.
Sediyanto, a forecaster at the BMKG Tanjung Emas Maritime Station in Semarang, stated that high waves of 1.25-2.5 metres are occurring fairly evenly across all northern waters of Central Java, such as Pekalongan-Kendal, Semarang-Demak, Karimunjawa, Jepara and Pati-Rembang, posing considerable risk to shipping activities.
In the southern waters of Central Java, Sediyanto noted that high waves are also occurring in all waters from Cilacap to Purworejo, despite the generally sunny and cloudy weather. “Be alert to high waves above 1.25 metres and when wind speeds exceed 15 knots while sailing,” he said.
In addition to the high waves, Sediyanto urged residents in coastal areas of several regions along the northern coast of Central Java to remain vigilant for ongoing flooding caused by tidal surges (rob) in the northern waters, with a maximum height of 1 metre between 10:00 and 14:00 WIB.
Sediyanto added that the tidal flooding in the northern waters, besides inundating dozens of villages in several areas, will also disrupt the activities of residents along the Pantura, including transportation, loading and unloading of goods at ports, inland fisheries and salt farming.
