Temperature

August's transformation into September witnesses an average high-temperature of a still hot 88.3°F (31.3°C), noting a minor change from the preceding month. September's average low-temperature reading in Arcadia settles at a moderately hot 74.3°F (23.5°C).

Heat index

September's mean heat index is evaluated at a blisteringly hot 107.6°F (42°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Exposure to the sun directly might heighten the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is a value derived by merging air temperature with the humidity to convey how the climate feels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to 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.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Avoid direct sunlight between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Keep in mind that shade structures may not provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
