March weather forecast
Calcutta, Belize

March, the first month of the spring in Calcutta, is also a moderately hot month, with temperature in the range of an average high of 29.8°C (85.6°F) and an average low of 21.4°C (70.5°F).

Temperature

March commences with an average high-temperature of a still moderately hot 29.8°C (85.6°F), showing little deviation from February's 28.8°C (83.8°F). In March, Calcutta encounters an average low-temperature of 21.4°C (70.5°F) during the night.

Heat index

In March, the average heat index is calculated to be a sweltering 36°C (96.8°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is a crucial mechanism for the human body, allowing it to release excessive warmth through evaporating sweat. 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. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

UV index

March through July and September, with an average maximum UV index of 7, are months with the highest UV index in Calcutta. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for the average person.
Note: The maximum daily UV index of 7 in March converts into the following recommendations:
Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
