Temperature

July, noted for its average high-temperature of 84.7°F (29.3°C) and an average low-temperature of 68°F (20°C), is considered the warmest month.

Heat index

The average heat index in July is computed to be a sweltering 95°F (35°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Keep in mind the heat index values are meant for areas in shade and with light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is found by incorporating humidity levels into the air temperature measurement. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to 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.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
