Weather in August
Temperature
In Vale, August records the highest average temperatures, peaking at 28.8°C (83.8°F) and reaching a low of 14.3°C (57.7°F).Heat index
The heat index value for August is computed to be a tropical 31°C (87.8°F). Staying active during long-term exposure might result in a state of exhaustion and cause heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
