Weather in September
Temperature
The transition into September is marked with an average high-temperature of a still hot 34.8°C (94.6°F), showing an insignificant shift from August's 33.7°C (92.7°F). Viçosa do Ceará registers a significant drop in temperature in September, with average nighttime lows of 21.5°C (70.7°F).Heat index
During September, the heat index is calculated to be an extremely hot 44°C (111.2°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.Remember that heat index calculations are made for conditions in the shade with light wind. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level 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 important for children. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. 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. As body temperatures escalate without effective heat release, one might face dehydration threats.
