Weather in September
Temperature
The arrival of September sees an average high-temperature of a still tropical 33.9°C (93°F), hardly diverging from August's 33.7°C (92.7°F). Birkelane's nights in September cool down to an average low-temperature of 24.8°C (76.6°F).Heat index
During September, the heat index is estimated at a blazing hot 48°C (118.4°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'felt air temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
