Weather in July
Temperature
July brings a slight increase in the average high-temperature, progressing from a pleasant 72.7°F (22.6°C) in June to a warm 80.6°F (27°C). Cornelius's average nighttime temperature descends significantly from the day's peak in July, settling at a fresh 53.4°F (11.9°C).Heat index
Throughout July, the heat index is estimated at 82.4°F (28°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Always consider that heat index estimations are for light winds and places in the shade. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
