Weather in May

The last month of the spring, May, is another hot month in Welikada, Sri Lanka, with an average temperature fluctuating between 30.8°C (87.4°F) and 26.4°C (79.5°F).

Temperature

The initiation of May sees an average high-temperature of a still hot 30.8°C (87.4°F), showing minor variations from the previous month. Nighttime temperatures in Welikada hover around an average low of 26.4°C (79.5°F) in May, a slight descent from daytime highs.

Heat index

For most parts of May, the heat index is calculated to be a blisteringly hot 40°C (104°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Note: The daily maximum UV index of 6 in May interprets into the following advice:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Avoid direct Sun exposure and seek shade between 10 a.m. and 4 p.m., when UV radiation is at its peak, but keep in mind that not all shade structures provide complete protection. To cut down UV radiation exposure by about half, sport a wide-brim hat.
