Weather in September
Temperature
September signals a slight drop in average high-temperature, sliding from August's hot 88.5°F (31.4°C) to a moderately hot 82.9°F (28.3°C). Belmont, during September, witnesses an average low-temperature of 63.5°F (17.5°C).Heat index
September's mean heat index is computed to be a tropical 89.6°F (32°C). With sustained exposure and activity, exhaustion becomes probable, resulting in heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a measure of how hot it feels when the actual air humidity is factored in. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
