Weather in September
Temperature
Várzea Branca records a slight change with September's average high-temperatures adjusting to a still tropical 32.3°C (90.1°F) from August's 30.8°C (87.4°F). During September nights, Várzea Branca records an average temperature of 21.1°C (70°F).Heat index
In September, the heat index is calculated to be a very hot 35°C (95°F). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an aggregate value of air's warmth and moisture to show the human-felt temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
