Weather in July
Temperature
July, noted for its average high-temperature of 89.8°F (32.1°C) and an average low-temperature of 73°F (22.8°C), is considered the warmest month.Heat index
Throughout July, the heat index is estimated at a blisteringly hot 109.4°F (43°C). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
