A slight uplift in the average high-temperature marks March in Chittagong, Bangladesh, adjusting from February's moderately hot 27.3°C (81.1°F) to a tropical 30.3°C (86.5°F). Chittagong experiences an average temperature drop to a pleasant 21.6°C (70.9°F) during March nights.

Heat index

The heat index value during March is evaluated at a very hot 35°C (95°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 highly critical to 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.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
