Central Java Weather Forecast for 11 June: Decreasing Tidal Floods, Partly Cloudy All Day

Sunny weather throughout the day in Central Java on Thursday (11/6) highlights a stark contrast in air temperature between day and night. Tidal flooding has decreased, but high waves persist in the northern and southern waters, warranting caution. From morning until early evening, the weather in 35 areas of Central Java—including mountainous regions, highlands, and lowlands—will be sunny and cloudy. Winds are blowing from the east to the south at speeds of 3 to 27 kilometres per hour, air temperatures range from 18 to 34 degrees Celsius, and humidity levels are between 50 and 95 per cent. Tidal flooding in the northern waters of Central Java has decreased dramatically to 0.8 per cent, although it still causes flooding in coastal areas. High waves in the southern waters range from 1.25 to 2.5 metres, posing a considerable risk to shipping activities such as fishing boats, barges, and cargo and passenger transport when wind speeds exceed 15 knots. “Central Java is beginning to enter the dry season, rainfall has significantly reduced, and the weather is sunny and cloudy throughout the day,” said Arif Nasution, a forecaster at the BMKG Semarang Meteorology Station, on Thursday (11/6). Entering this dry season, according to Arif, a noticeable temperature difference occurs between day and night, feeling hot and sultry during the day and experiencing extreme cold at night, not only in mountainous areas and highlands but also in lowlands. Retna Swasti Karibia, a forecaster at the BMKG Tanjung Emas Maritime Station in Semarang, stated that tidal flooding in the northern waters has decreased compared to before. However, flooding in coastal areas in several regions along the northern coast of Central Java still occurs, with a height of 0.8 metres between 13.00 and 18.00 WIB. Retna Swasti Karini added that wave heights in the northern waters of 0.5 to 1.25 metres are relatively safe for shipping activities. However, in the southern waters of Central Java, such as Cilacap, Kebumen, and Purworejo, wave heights of 1.25 to 2.5 metres pose a significant risk to shipping activities. “But remain vigilant about wave heights in the southern waters, especially when wind speeds exceed 15 knots,” she urged.
