Weather in July
Temperature
July is the month that records the highest temperatures, with averages ranging from a high of 80.8°F (27.1°C) to a low of 64.6°F (18.1°C).Heat index
July's mean heat index is computed to be a hot 87.8°F (31°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sunlight can potentially raise the heat index by 15 Fahrenheit (8 Celsius) degrees, so it's crucial to consider. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
