June weather forecast
Divulapitiya, Sri Lanka

June brings about the highest rainfall levels in Divulapitiya with 231mm (9.09"), setting the stage for the peak monsoon season. Despite the considerable amount of rainfall, it does not notably impact the overall temperature, maintaining a relatively stable range. The increased rainfall, high humidity, and frequent winds define June's weather. Tropical thunderstorms are a common sight during this period, offering a dramatic weather spectacle that is unique to tropical climates. As the weather gradually shifts, it marks the emergence of new weather patterns, ushering in the latter half of the year.

Temperature

A minor adjustment in Divulapitiya's average high-temperature is noted with the start of June, touching a warm 29.6°C (85.3°F) from May's 30.8°C (87.4°F). An average low-temperature of 25.9°C (78.6°F), slightly less than the daytime peak, marks the month of June.

Heat index

For June, the heat index is calculated to be a torrid 37°C (98.6°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Always consider that heat index estimations are for light winds and places in the shade. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Guard oneself from overexposure. Defence against sun injury is vital. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
