Munnar records high UV Index amid sharp temperature fluctuations

Munnar continues to record high ultraviolet (UV) index , which is the level of UV radiation from the sun on a scale of one to 11, even as low morning temperatures persist. According to the Kerala State Disaster Management Authority (KSDMA), a high UV index of 8 was reported on Monday, followed by a level of 7 on Tuesday. KSDMA data indicate that the UV index has remained consistently elevated in the region for several days.

Climatologist Gopakumar Cholayil cautioned that the sustained high UV index warrants precautionary measures. “Those working in open plantations must wear loose clothing that adequately covers the face and body. Prolonged exposure to excessive heat and high UV levels could disrupt the ecosystem in high-range forest areas, potentially driving wild animals into human settlements in search of food and water,” he said.

He further noted that as tourism is Munnar’s primary source of income, reports of high UV levels and rising heat could discourage visitors. “If this climate pattern persists, tourists may opt for alternative destinations,” he added.

Meanwhile, the hill station continues to experience cold mornings, which is contrasted with intense daytime heat.

Data from the United Planters Association of South India (UPASI) Tea Research Foundation show that the lowest temperature of 3°C was recorded at Chundavurrai on Tuesday, where the daytime temperature rose to 21°C. Temperatures dipped to 4°C at the UPASI headquarters in Nallathanni and in Devikulam, while 5°C was recorded in the Seven malai and Silent Valley areas. The highest daytime temperature of 27°C was reported at Seven malai.

Despite these fluctuations, sources in the plantation sector stated that no tea crop losses have been reported so far.

“Night and early morning temperatures remain extremely cold, which is a major attraction for visitors. Tourist arrivals have not declined and are expected to remain steady through February. Compared to other regions, Munnar continues to record significantly lower night and morning temperatures, sustaining its appeal among tourists,” Dileep Pottankulam, president of the Munnar Hotel and Resort Association, said.

In view of rising daytime temperatures in the hilly district, the District Labour Officer has rescheduled working hours. Until May 20, outdoor workers must observe a mandatory break from 12 p.m. to 3 p.m., and establishments have been directed to adjust shifts accordingly. Authorities have warned that strict action will be taken against violations of these directives.
