Weather in August
Temperature
August is the warmest month, with an average high-temperature of 30.8°C (87.4°F) and an average low-temperature of 23.9°C (75°F).Heat index
For August, the heat index is appraised at a sweltering 39°C (102.2°F). Incorporate additional preventive steps, heat exhaustion and heat cramps are possible. Long-lasting activity may cause heatstroke.One should be cognizant that the heat index values are tailored for shaded spots and mild winds. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the outcome of merging air's temperature and its humidity metrics. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
