Weather in September
Temperature
On the advent of September, Lake Pasadena Heights's average high-temperature exhibits a minor adjustment to a still tropical 88.2°F (31.2°C) from August's 90.1°F (32.3°C). An average low-temperature of 73.8°F (23.2°C) is observed during the September nights.Heat index
The heat index in September is estimated at a blistering 105.8°F (41°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children often miss understanding the importance of rest and rehydration. Thirst usually appears late during dehydration - therefore, maintaining hydration, particularly during long physical activities, is essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Guard oneself from overexposure. Defence against sun injury is vital. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
