Hyderabad is bracing for increasingly severe summers, with projected temperature increases significantly impacting the city. Analysis of past data and climate models indicates a consistent warming trend. The average maximum temperature during summers (March-May) has risen from 32.6°C in 1980-1990 to 35.8°C in 2010-2020.
Projections for 2026 suggest a further increase, potentially reaching an average maximum temperature of 37.2°C during the summer months. This translates to a potential increase of 1.4°C compared to the 2010-2020 average. The number of ‘heatwave’ days (temperatures exceeding 40°C) is also expected to rise dramatically. Currently, Hyderabad experiences around 20-25 heatwave days annually. By 2026, this could increase to 30-40 days.
The analysis highlights a particularly concerning trend: the increase in nighttime temperatures. Minimum temperatures are not cooling sufficiently, leading to increased discomfort and health risks. This is attributed to urban heat island effects, caused by concrete structures retaining heat.
Specific areas within Hyderabad are predicted to experience varying degrees of warming. Areas with limited green cover and dense concrete construction are expected to be more vulnerable. The report emphasizes the need for mitigation strategies, including increasing green spaces, promoting water conservation, and implementing cool roof technologies.
The study utilizes data from the India Meteorological Department (IMD) and climate models to create these projections. It underscores the urgency of addressing climate change and implementing adaptation measures to protect public health and infrastructure in Hyderabad. The increasing temperatures pose risks to vulnerable populations, including the elderly, outdoor workers, and those with pre-existing health conditions. The report serves as a warning and a call to action for city planners and policymakers.
