Weather in July
Temperature
Temperature readings reach their annual highs in July, averaging 87.1°F (30.6°C) and a minimum average of 64°F (17.8°C).Heat index
During July, the heat index is evaluated at a sweltering 100.4°F (38°C). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Sunshine
The average sunshine in July is 10h.UV index
May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: A maximum high daily UV index of 6 during July translates into the following directions:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
