Weather in July
Temperature
July, recognised by an average high temperature of 89.6°F (32°C) and a low of 69.1°F (20.6°C), is New Johnsonville's warmest month.Heat index
July's heat index is computed to be an extremely hot 109.4°F (43°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. 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 remain especially vital for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
