July weather forecast
Weerawila, Sri Lanka

July, like June, is another hot summer month in Weerawila, Sri Lanka, with an average temperature ranging between min 26.3°C (79.3°F) and max 30.7°C (87.3°F).

Temperature

The onset of July manifests an average high-temperature of a still hot 30.7°C (87.3°F), demonstrating a minor variation from the preceding month. July nights reflect a consistent temperature dip to a moderately hot 26.3°C (79.3°F), a slight descent from daytime peaks.

Heat index

July's mean heat index is evaluated at a fiery hot 38°C (100.4°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

UV index

The months with the highest UV index are January through September, November and December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for ordinary individuals.
Note: A daily high UV index of 7 in July leads to these guidelines:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. The Sun's UV radiation is most potent between the hours of 10 a.m. and 4 p.m. Try to avoid direct sunlight during this time. A wide-brimmed hat provides unparalleled sun protection for sensitive areas like the eyes, ears, and neck.
