Weather in July
Temperature
The warmest temperatures occur during July, when averages reach a peak of 87.8°F (31°C) and a low of 69.4°F (20.8°C).Heat index
During July, the heat index is appraised at a very hot 98.6°F (37°C). Exercise extra preventive actions, heat cramps and heat exhaustion are plausible. Continuous activity could result in heatstroke.Always consider that heat index estimations are for light winds and places in the shade. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values hold particular importance for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
