Sussex's July weather, marked by an average high temperature of 82.6°F (28.1°C) and an average low temperature of 61.3°F (16.3°C), is the warmest in the year.Heat index
July's mean heat index is computed to be a tropical 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.When assessing, remember that heat index measurements are for light winds and shaded spots. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. 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.
