Weather in September
Temperature
The onset of September is marked by a minor decrease in temperature, transitioning from a very hot 97.9°F (36.6°C) in August to a tropical 90.5°F (32.5°C). During the month of September, Hebbronville's nighttime temperature lowers to an average of 74.1°F (23.4°C).Heat index
The heat index in September is appraised at a blisteringly hot 105.8°F (41°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Always consider that heat index estimations are for light winds and places in the shade. Being exposed to direct sunshine might trigger a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
