Kerala Faces Blistering Heat, High UV Levels Amid Urban Heat Island Effect
The India Meteorological Department (IMD) has warned of above-average temperatures across Kerala, with sweltering conditions and high humidity expected to persist until early May. Temperatures in Palakkad recently exceeded 40°C, while other districts like Kollam and Kottayam face highs between 38°C and 39°C. Coastal areas are experiencing oppressive sultriness due to elevated relative humidity, significantly increasing the 'feels-like' temperature. Scientists report alarming Ultraviolet (UV) radiation levels, with indices reaching 8–9, posing serious health risks such as sunburn and eye damage. The situation is exacerbated by the urban heat island effect, where concrete and asphalt infrastructure raise city temperatures by up to 2°C compared to rural areas. Despite these harsh conditions, IMD officials state that a formal heatwave declaration is unlikely this year. This is attributed to a weak La Niña climate pattern, which is expected to bring increased summer rainfall by month's end, preventing temperatures from meeting the strict criteria for a heatwave. Residents are advised to take precautions against the intense heat and UV exposure during this peak summer period.
