Weather in April
Temperature
Alinjivakkam, India, records a slight change with April's average high-temperatures adjusting to a very hot 35.3°C (95.5°F) from March's 32.8°C (91°F). In Alinjivakkam, April nights cool down to an average of 27.3°C (81.1°F).Heat index
For April, the heat index is estimated at a life-threatening hot 50°C (122°F). Remain cautious: Heat cramps along with heat exhaustion are foreseeable. Ongoing activity may precipitate heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
