September's arrival comes with a mild decrease in the average high-temperature, moving subtly from a hot 89.8°F (32.1°C) in August to a moderately hot 82.4°F (28°C). In Oakland, the nighttime temperature registers a significant drop from daytime peaks to an average of 60.3°F (15.7°C) in September.Heat index
The heat index in September is estimated at a tropical 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.

Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
