Weather in July
Temperature
July, noted for its average high-temperature of 81.3°F (27.4°C) and an average low-temperature of 63.3°F (17.4°C), is considered the warmest month.Heat index
The heat index for July is computed to be a tropical 87.8°F (31°C). When exposure and activity are sustained, they could induce fatigue, with a chance of heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
