The Arjuna Temple area in Dieng Kulon Village, Dieng Plateau,\nBanjarnegara Regency, Central Java, has frozen and become covered in\nfrost. The phenomenon of frost, or \u2018bun upas\u2019, has blanketed the Dieng\narea in recent days alongside the arrival of the dry season, causing\ntemperatures there to touch minus 1 degree Celsius.<\/p>\n
The Secretary of Dieng Kulon Village, Sabar Alfarisi, stated that the\nappearance of frost has been visible for the past few days as air\ntemperatures continue to decrease from night to morning. \u201cFor\napproximately the last three days, frost has begun to appear in Dieng.\nIt is visible around the Arjuna Temple area and several other open\nareas,\u201d he said on Tuesday (9\/6\/2026) afternoon.<\/p>\n
According to him, this natural phenomenon, which is a hallmark of the\ndry season in Dieng, always attracts the attention of tourists.\nConsequently, many visitors arrive in the early hours of the morning to\nwitness and capture the formation of thin ice crystal layers on the\nsurface of grass and plants.<\/p>\n
\u201cMany tourists have arrived to see and photograph the frost. This\nphenomenon is indeed always a unique attraction for visitors to Diint,\u201d\nhe said.<\/p>\n
The Head of the Meteorology, Climatology, and Geophysics Agency\n(BMKG) Central Java Climatology Station, Goeroeh Tjiptanto, said the\nemergence of \u2018bun upas\u2019 this year was triggered by dry weather\nconditions in recent days. Based on BMKG data, rainfall in the Dieng\narea during the period of 6-9 June 2026 was recorded at 0\nmillimetres.<\/p>\n
\u201cZero millimetres of rainfall indicates that the atmosphere is in a\nvery dry condition. Additionally, the sky tends to be clear without\nclouds from night to morning,\u201d he said.<\/p>\n
He explained that the lack of cloud cover allows the heat stored on\nthe earth\u2019s surface during the day to be released maximally into the\natmosphere and space at night. According to him, this condition causes\nthe cooling process to occur rapidly, resulting in a drastic drop in\nground surface temperatures.<\/p>\n
\u201cBased on data, the minimum air temperature in Dieng on 9 June 2026\nreached 1.05 degrees Celsius at 01:01 WIB. Meanwhile, the temperature of\nthe grass or ground surface was recorded even lower, at 0.60 degrees\nCelsius at 08:30 WIB,\u201d he said.<\/p>\n
He added that these conditions allow for the formation of thin ice\ncrystal layers on grass, agricultural plants, and other surfaces\ndirectly exposed to the cold air. He noted that the topography of Dieng,\nwhich consists of a basin surrounded by mountains, further strengthens\nthe formation of frost.<\/p>\n
\u201cCold air from the mountain slopes moves downwards at night and\nbecomes trapped in the valley floor, causing the temperature in the area\nto be much lower than in surrounding regions,\u201d he said.<\/p>\n
In relation to this, Goeroeh urged the public and tourists visiting\nDieng to prepare warm clothing and to be wary of extreme cold\ntemperatures, which are expected to potentially continue for the next\nfew days, especially from night to morning.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/dieng-plateau-freezes-over-temperatures-drop-to-minus-1-degree-celsius-1781009753", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
