Weather in July
Temperature
July's advent notes a subtle adjustment in average high-temperature to a still sweltering 99.7°F (37.6°C) from June. Nightly temperatures drop to an average low of 78.8°F (26°C) in July.Heat index
For most parts of July, the heat index is appraised at a burning hot 120.2°F (49°C). Observe: Heat exhaustion and heat cramps are probable. Heatstroke is on the horizon with prolonged exertion.Heat index guidelines indicate values are for light wind scenarios and shaded regions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', blends air temperature and moisture content to represent the felt temperature to humans. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
