Weather in July
Temperature
The warmest period tends to be July, when average temperatures fluctuate between a high of 86.4°F (30.2°C) and a low of 64.9°F (18.3°C).Heat index
For July, the heat index is evaluated at a torrid 98.6°F (37°C). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.Understand that the heat index values take into account shaded locations and mild winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.
