Weather in July
Temperature
With average high temperatures of 80.8°F (27.1°C) and lows of 63.7°F (17.6°C), July is the warmest month.Heat index
July's average heat index is calculated to be a tropical 86°F (30°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Heat index determinations are made taking into account the shade and light air movements. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. 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.
