The heat index in July is computed to be a tropical 87.8°F (31°C). If one continues to be active during exposure, it might cause tiredness and subsequent heat cramps.It is important to note that the heat index values are for shaded areas and light wind scenarios. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.

When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children.
