Weather in July
Temperature
During the warmest month, July, temperatures average a high of 81.3°F (27.4°C) and a low of 65.8°F (18.8°C).Heat index
In July, the average heat index is evaluated at a tropical 87.8°F (31°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.One should consider that heat index numbers are for shaded settings and light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
