The Public Relations Officer of TNBTS, Endrip Wahyutama, stated that the frost phenomenon frequently occurs every year in mountainous regions. This condition usually appears near the dry season.

Tips for Tourists
Endrip advised that due to the cold temperature, tourists should better prepare themselves when visiting Ranu Pani, Ranu Regulo, or Mount Bromo. Wear thick clothing, jackets, gloves, and head covers. These items are important to prevent tourists from getting hypothermia.
Furthermore, he reminded all tourists to preserve the environment in the Bromo Tengger Semeru National Park area.
"We remind everyone not to touch or step on plants covered with frost, in order to preserve the ecosystem and avoid damage to the vegetation and natural landscape," he said.
