May weather forecast
Bobella, Sri Lanka

The last month of the spring, May, is another hot month in Bobella, Sri Lanka, with an average temperature fluctuating between 24.5°C (76.1°F) and 34.2°C (93.6°F).

Temperature

The shift into May reveals an average high-temperature of a still tropical 34.2°C (93.6°F), closely mirroring April's climate. Nighttime temperature experiences an average drop to a warm 24.5°C (76.1°F) in May.

Heat index

The heat index in May is computed to be a blazing hot 49°C (120.2°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.
Understanding the heat index involves considering values for shaded locales with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Humidity

In May, the average relative humidity is 72%.

Rainfall

In Bobella, in May, during 17.4 rainfall days, 83mm (3.27") of precipitation is typically accumulated. In Bobella, during the entire year, the rain falls for 196.8 days and collects up to 943mm (37.13") of precipitation.

UV index

The months with the highest UV index are February through October, with an average maximum UV index of 7. A UV Index estimate of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.
Note: The maximum UV index of 7 during May leads to these instructions:
Prevent overexposure. Protection from the sun's harmful effects is needed. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
