Weather in September
Temperature
As Rodolfo Fernandes welcomes September, the average high-temperature is noted at a fiery hot 35.6°C (96.1°F), closely aligning with the preceding month. With a significant temperature contrast, nighttime temperatures hover around an average low of 22.5°C (72.5°F) in September.Heat index
For most parts of September, the heat index is computed to be an extremely hot 44°C (111.2°F). Prudent: Heat cramps and heat exhaustion are likely. Heatstroke becomes imminent with sustained exertion.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Sweat evaporation, driven by perspiration, is the method the human body uses to rid itself of excessive warmth. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. As body temperatures escalate without effective heat release, one might face dehydration threats.
