Weather in September
Temperature
In La Grulla, the beginning of September is marked by a marginally lowered average high-temperature, shifting from August's sweltering 99.9°F (37.7°C) to a tropical 92.8°F (33.8°C). La Grulla records an average low-temperature of 77.2°F (25.1°C) throughout the month of September.Heat index
For most parts of September, the heat index is appraised at a blisteringly hot 109.4°F (43°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. 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 babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
