Weather in July
Temperature
July, characterized by an average high temperature of 84°F (28.9°C) and a low temperature of 66.7°F (19.3°C), is generally the warmest month.Heat index
The heat index value during July is computed to be a fiery hot 95°F (35°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Know that the heat index computations account for shaded terrains and slight winds. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

June through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health risk from unprotected exposure to Sun's UV rays for the average person.Note: The UV index of 6 in July translates into these instructions:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays.
