Munnar continues to record a high ultraviolet (UV) index, which is the level of UV radiation from the sun on a scale of one to 11, even as cool 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 indicates that the UV index remained persistently elevated in the region for several days.
Climatologist Gopakumar Cholayil warned that the persistently high UV index calls for 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 levels of UV radiation could disrupt the ecosystem in high-range forest areas and potentially drive wild animals into human settlements in search of food and water,” he said.
He further noted that since tourism is Munnar’s main 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 cool mornings, contrasting with the intense daytime heat.
Data from the United Planters Association of South India (UPASI) Tea Research Foundation shows that a low of 3°C was recorded in Chundavurrai on Tuesday, where the day temperature rose to 21°C. Temperatures dropped to 4°C at UPASI headquarters in Nallathanni and Devikulam, while 5°C was recorded in Seven Malai and Silent Valley areas. The highest daily temperature of 27°C was reported in Seven malai.
Despite these fluctuations, sources in the plantation sector said no loss of tea crop has been reported so far.
“Night and early morning temperatures remain extremely low, which is a major attraction for visitors. Tourist arrivals are not declining and are expected to remain stable till February. Compared to other regions, Munnar continues to record significantly lower night and morning temperatures, which maintains its appeal among tourists,” said Dileep Pottankulam, President, Munnar Hotel and Resort Association.
Due to the rising daytime temperatures in the hilly district, the district labor office has postponed the working hours. Outdoor workers must observe a mandatory break from 12pm to 3pm until May 20 and establishments have been ordered to adjust their shifts accordingly. Authorities have warned that strict action will be taken against violations of these guidelines.
