Weather in July
Temperature
The warmest month is July, with an average high-temperature of 85.6°F (29.8°C) and an average low-temperature of 64°F (17.8°C).Heat index
Throughout July, the heat index is calculated to be a fiery hot 96.8°F (36°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is achieved by amalgamating air temperature with the relative humidity readings. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
