Weather in July
Temperature
July is the warmest month of the year, registering average temperatures as high as 82°F (27.8°C) and as low as 59.9°F (15.5°C).Heat index
The heat index in July is computed to be a tropical 87.8°F (31°C). Constant exposure and activity lead to possible fatigue. Prolonged exercise may result in heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
