Weather in September

September, the first month of the autumn in Fremont, is still a tropical month, with an average temperature varying between 67.1°F (19.5°C) and 87.6°F (30.9°C).

Temperature

The advent of September brings an average high-temperature of a still hot 87.6°F (30.9°C), almost identical to the preceding month. Fremont's average low-temperature in the month of September is recorded at a comfortable 67.1°F (19.5°C).

Heat index

In September, the heat index is evaluated at a very hot 100.4°F (38°C). Incorporate extra safety measures to avoid heat exhaustion and heat cramps. Continuous activity could provoke heatstroke.
Data suggests that the heat index is set for environments in shade and with a light wind. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', arises from combining readings of air temperature and relative moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young children are generally more endangered than adults, as they usually less sweat. And also, due to larger skin surface relative to their small bodies and higher heat production as a result of their activity.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
