Weather in July
Temperature
With average temperatures fluctuating between a high of 93°F (33.9°C) and a low of 71.2°F (21.8°C), July stands out as the warmest month.Heat index
For most parts of July, the heat index is appraised at a very hot 98.6°F (37°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Remember that heat index calculations are made for conditions in the shade with light wind. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', blends air temperature and moisture content to represent the felt temperature to humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
