Residents of Jember Regency have been experiencing unusually high temperatures over the past few days. The temperature dropped drastically to 19 degrees Celsius in the morning. This cold phenomenon has disrupted residents’ daily activities. Responding to this phenomenon, Dr. Luffi Rohman, a Lecturer in Master’s Degree in Physics at the Faculty of Mathematics and Natural Sciences (FMIPA), explained that the cold temperatures are caused by two main factors: the Earth’s position at aphelion (the point furthest from the sun) and the still-high rainfall. “When the Earth is at aphelion, the distance between the Earth and the sun reaches its maximum, so the amount of solar radiation received is reduced. On the other hand, high humidity from rain also amplifies the cooling effect on the surface,” he explained.
He explained that this cold temperature generally occurs in the middle of the year and is a natural phenomenon, but it still requires vigilance regarding its impact on public health. Aphelion itself is a point in the Earth’s elliptical orbit around the sun, where the distance between the Earth and the sun reaches approximately 152 million kilometers, compared to the perihelion point (closest distance) of only about 147 million kilometers. “The still-high rainfall in the Jember region contributes to increased air humidity, which amplifies the cooling effect. The combination of low solar radiation and high humidity creates cooler temperatures than usual,” Lutfi continued.
He urged residents to always wear warm clothing, maintain nutritional intake, and limit outdoor activities at night. “For children, the elderly, and those with certain medical conditions, it is important to pay attention to their physical condition and not force themselves to engage in activities in low temperatures without adequate protection,” he added when met in the Dean’s Room of the Faculty of Mathematics and Natural Sciences, UNEJ. This phenomenon of extreme cold temperatures is expected to continue for some time. Local governments and health services are expected to participate in educating the public to be better prepared for these extreme weather changes.
As reported by several media outlets, residents complained about the cold temperatures, forcing them to wear thick clothing, layered jackets, and even head coverings to keep warm. Even simple activities like sweeping the yard are now done in thick clothing. “Usually I just wear my house clothes in the morning, but now I have to wear a thick jacket because the cold is unbearable,” said one Kaliwates resident, while sweeping his yard.
Not only housewives, but other residents are also trying to combat the cold by doing light exercise like jogging and brisk walking in the morning. This is done to maintain a stable body temperature. However, these low temperatures still pose health risks, especially for those who are sensitive to cold air, such as those with allergies and respiratory disorders. Common symptoms include runny noses, sneezing, and nasal congestion.
