Weather in June
Temperature
Vannivilankulam, Sri Lanka, records an average high-temperature of a still hot 30.5°C (86.9°F) in June, maintaining a close correlation with May's 31.2°C (88.2°F). Throughout June, Vannivilankulam reports a steady low-temperature average of 27.8°C (82°F), slightly lower than its daytime counterpart.Heat index
June's average heat index is estimated at a sweltering 38°C (100.4°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', determines the feeling of heat when you account for the relative humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.
Humidity
The average relative humidity in June is 76%.Rainfall
The month with the least rainfall is June, when the rain falls for 11.3 days and typically collects 28mm (1.1") of precipitation.Daylight

January through October and December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for ordinary individuals.Note: In June, the maximum UV index of 7 suggests these recommendations:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. 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. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
