Extreme heat grips Kerala as night temperatures stay high; low rainfall raises concerns

THIRUVANANTHAPURAM: Kerala is facing intense and unusual heat, with scorching daytime temperatures and little relief even at night. Early mornings are also humid, and the heat remains so strong that even fans and air conditioners are struggling to provide comfort. The state, once known for its pleasant climate, is now experiencing extreme weather changes.

The main reasons are reduced wind flow and weak summer rains. Though a heatwave has not been officially declared, conditions are similar. Buildings heated during the day are not cooling down at night, making it difficult for people to stay indoors. Palakkad has recorded the highest temperatures, touching 40 degrees Celsius on three days this month.

Electricity consumption has increased sharply as people use fans and air conditioners continuously. Daily usage is about 8 million units higher than last year, leading to unannounced power cuts in some areas.

From March 1 to April 19, Kerala should have received 95.6 mm of summer rain, but only 59 mm was recorded, a deficit of 38%. Palakkad had the lowest rainfall with a 63% deficit, while Kozhikode was the only district to receive excess rain at 22%. Light summer showers in some districts yesterday brought slight relief.

Reduced sea breeze, heat dome

1. The land, which heats up during the day, does not cool down at night, and the reduced flow of sea breeze towards the land is causing higher night temperatures. In addition, an anticyclone (high-pressure system) over northern Karnataka and Maharashtra is also contributing to the increased heat in Kerala.
2. Weather experts say the intense heat felt by the human body is due to the heat dome phenomenon. It occurs when a high-pressure area in the atmosphere traps hot air over a region like a lid. Even if the actual temperature is around 38°C, it can feel closer to 40°C because of this effect.

Heatstroke clinics in hospitals
To tackle heat-related health issues, government hospitals have started heat stroke clinics. These clinics provide treatment for sunstroke and dehydration, and are equipped with cooling devices, medicines, ORS, and ice packs.

Avoid prolonged exposure to direct sunlight

• Avoid prolonged exposure to direct sunlight. Drink water even if you are not feeling thirsty, and always carry drinking water to prevent dehydration.
• Avoid alcohol, coffee, tea, and carbonated soft drinks during the daytime.
• Use an umbrella or wear a hat when going outside.
• Eat plenty of fruits and vegetables. You can also have buttermilk. If you feel unwell, take a rest immediately and seek medical help.
