Real Feel Temperature in Delhi
Delhi is currently experiencing a severe heatwave. Temperatures have exceeded 45 degrees Celsius. The ‘real feel’ temperature has reached an alarming 51.9 degrees Celsius. This situation has prompted the India Meteorological Department (IMD) to issue a red alert. Residents face health risks due to extreme heat.
About Real Feel Temperature
Real feel temperature, also known as the heat index, combines air temperature and humidity. It indicates how hot it feels to the human body. High humidity hampers sweat evaporation. This makes it difficult for the body to cool down. In contrast, dry air allows for quicker evaporation, slightly easing heat stress.
Health Risks Associated with Extreme Heat
A heat index of 51.9 degrees Celsius falls into the ‘extreme danger’ category. Prolonged exposure can lead to heat stroke and exhaustion. The IMD warns vulnerable groups, including children and the elderly, to stay indoors. Hydration is crucial during such conditions.
Urban Heat Island Effect
Urban areas experience intensified heat due to the urban heat island effect. Concrete and asphalt absorb and radiate heat. This effect causes cities to remain warmer than surrounding rural areas. As a result, urban dwellers face increased heat stress.
Current Weather Conditions in Delhi
On June 12, Ayanagar recorded the highest temperature at 45 degrees Celsius. Other areas such as Palam and Ridge followed closely. The IMD has begun issuing experimental localised heat index alerts during heatwaves. However, the heat index is not formally tracked in India.
Weather Forecast and Relief Measures
The IMD predicts a shift in weather conditions starting June 12. Light rain and thunderstorms are expected. By June 18, temperatures may dip below 40 degrees Celsius. The public is advised to remain cautious during peak heat hours.
Heatwave Impact Beyond Delhi
The heat crisis extends to Punjab and Haryana, which are also under red alerts. Meanwhile, tourist destinations like Nainital are seeing increased visitors seeking respite. This has led to traffic congestion and overcrowding in these areas.
Monsoon Developments in India
While northern India suffers from heat, the southwest monsoon is becoming active in southern states. Kerala, Konkan, and Goa are experiencing intense rainfall. The monsoon is expected to reach Himachal Pradesh by June 20.
