Weather in July
Temperature
The month of July, characterized by an average high of 85.6°F (29.8°C) and a low of 68.5°F (20.3°C), is recognized as the warmest.Heat index
The average heat index in July is evaluated at a very hot 98.6°F (37°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Rising body temperatures due to excess heat retention could signify impending heat disorders.
