Throughout July, the heat index is estimated at a tropical 87.8°F (31°C). Prolonged exposure combined with continuous activity could lead to exhaustion, and possibly heat cramps.Note that heat index values are valued for light wind and location in the shade.

Note: The heat index, also known as 'real feel' or 'apparent temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children.

Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
