Weather in July
Temperature
The warmest period is July, when temperatures fluctuate between an average high of 88.3°F (31.3°C) and a low of 68.9°F (20.5°C).Heat index
July's mean heat index is appraised at a blisteringly hot 104°F (40°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Remember that heat index calculations are made for conditions in the shade with light wind. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 hold particular significance for children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
