Weather in September
Temperature
The commencement of September includes a gentle temperature shift, with the average high-temperature dropping a bit from a hot 88.3°F (31.3°C) in August to a moderately hot 81.9°F (27.7°C). Nighttime temperature in Corona dips to a mean of 60.8°F (16°C) during September.Heat index
For September, the heat index is calculated to be a tropical 86°F (30°C). Persisting in activity during exposure could lead to weariness and subsequently to heat cramps.Data suggests that the heat index is set for environments in shade and with a light wind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
