Uduwana experiences an average high-temperature of a warm 29.2°C (84.6°F) in June, subtly different from May's 30.3°C (86.5°F). Uduwana's nighttime average temperature in June drops marginally from the daytime highs, settling at 26.1°C (79°F).

Heat index

The average heat index in June is calculated to be a fiery hot 36°C (96.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.

UV index

The months with the lowest UV index in Uduwana are May, June, August and October, with an average maximum UV index of 6. A UV Index estimate of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: A daily high UV index of 6 in June leads to these guidelines:
Embrace precautions and observe sun safety norms. Evasion of sunburn is a necessity. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
