Weather in September
Temperature
Crowley's weather in September displays an average high-temperature of a still tropical 86.5°F (30.3°C), showing minor disparity from August's 90°F (32.2°C). During September nights, Crowley records an average temperature of 70.7°F (21.5°C).Heat index
Throughout September, the heat index is computed to be a sweltering 100.4°F (38°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Heat index's context suggests values are appropriate for shady areas and slight breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Awareness of direct sun exposure is crucial as it has the potential to heighten the weather's effects, pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
