August weather forecast
Arugam Bay, Sri Lanka

Weather in August in Arugam Bay occurs in sync with the prevailing summer rhythm. Even though there is a mild increase in rainfall, it does not disrupt the ongoing outdoor activities. The climate continues to be warm, which accommodates both sunbathers and watersports enthusiasts. In spite of the rise in humidity, the weather remains welcoming due to the constant sea temperatures. With August drawing to a close, a gradual change in the weather dynamic can be expected, hinting at the arrival of the monsoon season.

Temperature

August's average high-temperature is a still hot 32.3°C (90.1°F), maintaining a close comparison with July's 32.6°C (90.7°F). The average low-temperature of 25.8°C (78.4°F) is witnessed during August.

Heat index

The heat index value for August is evaluated at a scorching 41°C (105.8°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Humidity

In August, the average relative humidity is 70%.

Shun overexposure. Protection from sun ravages is indispensable. Minimize exposure to direct sunlight and seek shade from 10 a.m. to 4 p.m., when UV radiation is most intense, but remember that shade structures may not offer complete protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Be mindful! Sand and water reflections can up the Sun's UV exposure.
