Weather in May

May, the last month of the spring in Nawala, is another tropical month, with temperature in the range of an average low of 26.3°C (79.3°F) and an average high of 30.6°C (87.1°F).

Temperature

With May's advent, Nawala, Sri Lanka, sees an average high-temperature of a still tropical 30.6°C (87.1°F), subtly shifted from April's 31.8°C (89.2°F). Nawala's temperature during May nights registers a minor decrease to an average low of 26.3°C (79.3°F).

Heat index

During May, the heat index is evaluated at a blisteringly hot 40°C (104°F). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Take note of the fact that heat index values are based on shaded circumstances with light airflows. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', determines the feeling of heat when you account for the relative humidity. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
