Weather in July
Temperature
The warmest temperatures occur during July, when averages reach a peak of 89.2°F (31.8°C) and a low of 67.6°F (19.8°C).Heat index
The heat index value during July is appraised at an extremely hot 104°F (40°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Always consider that heat index estimations are for light winds and places in the shade. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. 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 are extremely significant for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. The hours from 10 a.m. to 4 p.m. have the most intense UV radiation. As much as possible, limit direct sun exposure during this period. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
