Weather in July
Temperature
July, noted for its average high-temperature of 80.6°F (27°C) and an average low-temperature of 64.9°F (18.3°C), is considered the warmest month.Heat index
The heat index value during July is calculated to be a hot 86°F (30°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical 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.
