Weather in August

The heat index value during August is computed to be a tropical 86°F (30°C). Constant activity during exposure could result in a state of weariness and possibly heat cramps.The metrics for the heat index are tailored for both shady environments and light winds. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
