Weather in July
Temperature
July is the warmest month, with an average high-temperature of 82.8°F (28.2°C) and an average low-temperature of 61.3°F (16.3°C).Heat index
For July, the heat index is calculated to be a tropical 89.6°F (32°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Bear in mind that the heat index values are determined for shaded areas and light breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
