Weather in September
Temperature
The onset of September marks an average high-temperature of a tropical 31.1°C (88°F), hardly differing from August's 29.5°C (85.1°F). In Poço Redondo, the average temperature during the nights of September drops to a refreshing 19.5°C (67.1°F).Heat index
In September, the average heat index is calculated to be a very hot 37°C (98.6°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.The metrics for the heat index are tailored for both shady environments and light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', shows a temperature sensation when both heat and moisture conditions are combined. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
