Weather in September
Temperature
September sees a slight reduction in average high-temperature, with a shift from a very hot 95.5°F (35.3°C) in August to a tropical 86.9°F (30.5°C). In September, Chico reports a consistent average low-temperature of 68°F (20°C) during the nights.Heat index
Throughout September, the heat index is appraised at a very hot 95°F (35°C). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Deter overexposure. Protecting against the sun's effects is essential. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
