Weather in August

August's heat index is estimated at a tropical 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Be aware that heat index ratings are designed for shaded locations and minor breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
