Weather in August
Temperature
Shifting into August, Isabella records an average high-temperature of a tropical 93°F (33.9°C), presenting minor fluctuations compared to the previous month. The low-temperature averages to an agreeable 73°F (22.8°C) during the nights of August.Heat index
In August, the average heat index is computed to be a blistering 104°F (40°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Data suggests that the heat index is set for environments in shade and with a light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
