April weather forecast
Adyar, India

April, like March, is another tropical pre-monsoon summer month in Adyar, India, with an average temperature ranging between max 34.8°C (94.6°F) and min 27.3°C (81.1°F).

Temperature

Transitioning into April, Adyar records an average high-temperature of a still hot 34.8°C (94.6°F), almost identical to March's 32.4°C (90.3°F). Nighttime temperature lowers to an average of 27.3°C (81.1°F) in April.

Heat index

The heat index value for April is evaluated at a life-threatening hot 49°C (120.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

In April, the average relative humidity is 68%.

Rainfall

In Adyar, in April, during 4.3 rainfall days, 10mm (0.39") of precipitation is typically accumulated. Throughout the year, there are 169.2 rainfall days, and 825mm (32.48") of precipitation is accumulated.

UV index

April through July, with an average maximum UV index of 8, are months with the highest UV index in Adyar. A UV Index estimate of 8 to 10 represents a very high health risk from unsafe exposure to UV radiation for ordinary individuals.
Note: A typical high UV index of 8 in April suggests the following recommendations:
Always take safety measures. The skin and eyes are at risk if left exposed. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
