Weather in July
Temperature
The arrival of July brings an average high-temperature of a still hot 91.4°F (33°C), nearly identical to June's 86.9°F (30.5°C). July brings Preston a consistent average low-temperature of 72.1°F (22.3°C).Heat index
July's heat index is calculated to be a scorching 109.4°F (43°C). Alert: Heat cramps and heat exhaustion are likely to occur. Prolonged exertion can lead to heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are especially vital to children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.
