Weather in July
Temperature
July, marked by an average high-temperature of 84.2°F (29°C) and a low-temperature of 63.7°F (17.6°C), is the warmest month.Heat index
July's heat index is appraised at a hot 93.2°F (34°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
