Weather in September
Temperature
Transitioning into September, Stockton records an average high-temperature of a still hot 87.1°F (30.6°C), almost identical to August's 90.9°F (32.7°C). Throughout September, a steady low-temperature average of 69.4°F (20.8°C) is noted.Heat index
Throughout September, the heat index is evaluated at a sweltering 102.2°F (39°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Consider that heat index readings are for situations in the shade and light wind. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
