Weather in July
Temperature
New Salem notes the warmest temperatures in July, with a high average of 84.4°F (29.1°C) and a low of 66.7°F (19.3°C).Heat index
The heat index value during July is estimated at a fiery hot 95°F (35°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.The standards for the heat index are set for locations in shade and under light breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
