March weather forecast
Kannanur, India

The first month of the pre-monsoon summer, March, is a torrid month in Kannanur, India, with an average temperature varying between 35.8°C (96.4°F) and 23.4°C (74.1°F).

Temperature

The advent of March reveals an average high-temperature of a very hot 35.8°C (96.4°F), showing minimal difference from the prior month. Kannanur's average nighttime temperature descends significantly from the day's peak in March, settling at a moderately hot 23.4°C (74.1°F).

Heat index

Throughout March, the heat index is evaluated at a life-threatening hot 46°C (114.8°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important 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 keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Swift harm can befall unprotected skin and eyes. Prioritize safety. The Sun's UV radiation is most intense from 10 a.m. to 4 p.m. Try to avoid direct sun exposure during these hours. During bright days, sunglasses that offer UVA and UVB defense are recommended.
