August weather forecast
Nedagamuwa, Sri Lanka

The last month of the summer, August, is also a moderately hot month in Nedagamuwa, Sri Lanka, with an average temperature fluctuating between 29.3°C (84.7°F) and 25.4°C (77.7°F).

Temperature

The advent of August denotes an average high-temperature of a still moderately hot 29.3°C (84.7°F), subtly different from July's 29.2°C (84.6°F). Nedagamuwa encounters a negligible difference from daytime peaks throughout the August nights, with a low-temperature average of 25.4°C (77.7°F).

Heat index

August's mean heat index is appraised at a very hot 36°C (96.8°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Humidity

The months with the highest humidity are June through August, with an average relative humidity of 82%.

UV index

May, June, August and October, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from unsafe exposure to UV radiation for the average person.
Note: In August, a daily maximum UV index of 6 leads to the following instructions:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses.
