Weather in July
Temperature
July is the warmest month, with an average high-temperature of 91°F (32.8°C) and an average low-temperature of 73.2°F (22.9°C).Heat index
The heat index value during July is evaluated at a life-threatening hot 113°F (45°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is a numerical representation of warmth when taking temperature and moisture levels into account. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters often neglect the necessity for rest and hydration. Thirst is a sign of advancing dehydration - thus the importance of maintaining hydration, specifically during long-lasting physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
