Weather in September

The first month of the autumn, September, is still a hot month in Humble, Texas, with an average temperature varying between 72.5°F (22.5°C) and 89.6°F (32°C).

Temperature

September's onset brings a negligible change in high-temperatures, falling from a fiery hot 95.5°F (35.3°C) in August to a hot 89.6°F (32°C). Humble's temperature in September lowers to a consistent average of 72.5°F (22.5°C) during the nights.

Heat index

The average heat index in September is evaluated at a blisteringly hot 107.6°F (42°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With an abundance of moisture present in the air, the process of evaporation becomes less effective, and the body fails to cool down as it should, leading to the sensation of overheating. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
