Weather in July
Temperature
July is the warmest month, with the temperature often reaching an average high of 87.8°F (31°C) and an average low of 68.5°F (20.3°C).Heat index

Prolonged activity may trigger heatstroke.Note that heat index values are valued for light wind and location in the shade. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. A person's impression of weather can be swayed by numerous aspects, among them metabolic variations, pregnancy, and activity levels. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
