March weather forecast
Vallam, India

March, the first month of the pre-monsoon summer in Vallam, is a fiery hot month, with an average temperature fluctuating between 23.4°C (74.1°F) and 35.4°C (95.7°F).

Temperature

As Vallam transitions into March, a marginal rise in the average high-temperature is observed, moving from a tropical 32.3°C (90.1°F) in February to a very hot 35.4°C (95.7°F). Vallam anticipates a considerable drop in temperature at night in March, with an average low of 23.4°C (74.1°F).

Heat index

Throughout March, the heat index is calculated to be a blazing hot 48°C (118.4°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Note that heat index values are valued for light wind and location in the shade. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
For the human body, perspiration is the go-to method to regulate temperature, using sweat's evaporation to dissipate warmth. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Humidity

The average relative humidity in March is 64%.

Rainfall

In March, the rain falls for 7.2 days. Throughout March, 19mm (0.75") of precipitation is accumulated. In Vallam, during the entire year, the rain falls for 145 days and collects up to 512mm (20.16") of precipitation.

Daylight

On the first day of the month, sunrise is at 6:28 am and sunset at 6:23 pm. On the last day of March, sunrise is at 6:11 am and sunset at 6:24 pm IST.

Sunshine

In March, the average sunshine is 9.4h.

UV index

The months with the highest UV index are March through August, with an average maximum UV index of 8. A UV Index reading of 8 to 10 represents a very high threat to health from unsafe exposure to UV radiation for average individuals.
Note: The maximum daily UV index of 8 in March interprets into the following recommendations:
Immediate damage can occur to skin and eyes if left unprotected. Always take necessary precautions. Remember that UV radiation from the Sun is strongest between 10 a.m. and 4 p.m. Make an effort to limit direct sun exposure during this time. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
