Weather in July
Temperature
July, known for its average high temperature of 89.8°F (32.1°C) and an average low temperature of 73°F (22.8°C), is the warmest month.Heat index
July's mean heat index is appraised at a blisteringly hot 109.4°F (43°C). Beware: Heat exhaustion along with heat cramps are on the cards. Heatstroke could result from sustained physical activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
