June weather forecast
Trincomalee, Sri Lanka

June rolls in, bringing an interesting twist to Trincomalee's weather narrative. Despite being midway through the year, there is a stark decline in rainfall to 15mm (0.59"). This decrease is coupled with a rise in the number of sunshine days, giving June its uniquely arid character. However, the rougher winds from the previous month persist, with speeds reaching up to 23.8km/h (14.8mph). The dominant dry and windy weather offers an exhilarating experience for water sport enthusiasts.

Temperature

June's advent presents an average high-temperature of a still tropical 33.6°C (92.5°F), indicating a slight variation from the conditions of the previous month. Trincomalee, in the month of June, anticipates a consistent average low-temperature of 24.8°C (76.6°F).

Heat index

The heat index for June is estimated at a blistering 44°C (111.2°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
For clarity, heat index numbers account for light winds and areas under shade. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
