Weather in August
Temperature
The warmest period tends to be August, when average temperatures fluctuate between a high of 29.8°C (85.6°F) and a low of 24.7°C (76.5°F).Heat index
The average heat index in August is computed to be a very hot 36°C (96.8°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The individual's experience of temperature can be shaped by numerous aspects such as metabolic variations, physical exertion, and attire. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. 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. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
