Weather in September
Temperature
September brings an average high-temperature of a warm 85.3°F (29.6°C), nearly identical to the preceding month. In the month of September, Gibson experiences an average low-temperature of 67.1°F (19.5°C).Heat index
For September, the heat index is computed to be a fiery hot 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Keep in mind the heat index values are meant for areas in shade and with light wind. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Elevated heat gain compared to the body's release capability poses risks of dehydration and potential overheating.
