Weather in August
Temperature
With an average high-temperature of 30.3°C (86.5°F) and an average low-temperature of 24.4°C (75.9°F), August is the warmest month.Heat index
August's average heat index is appraised at a sweltering 38°C (100.4°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Be advised, the heat index considers values for conditions in shade and with a light breeze. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
