Weather in March

March, the first month of the spring in Kolonnawa, is still a tropical month, with an average temperature fluctuating between 24.3°C (75.7°F) and 31.8°C (89.2°F).

Temperature

Kolonnawa's warmest season falls during March and April, averaging a high-temperature of 31.8°C (89.2°F).

Heat index

March's heat index is estimated at a blistering 42°C (107.6°F). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', shows a temperature sensation when both heat and moisture conditions are combined. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
