Weather in September
Temperature
Monte Bello experiences an average high-temperature of a warm 85.5°F (29.7°C) in September, subtly different from August's 90.1°F (32.3°C). During September, Monte Bello experiences a consistent low-temperature average of 65.7°F (18.7°C).Heat index
For September, the heat index is evaluated at a torrid 95°F (35°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Research indicates the heat index considers values in shaded locales and with light winds. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Proceed with care. Light skin individuals may be exposed to burns in fewer than 30 minutes. Considering the strength of solar radiation at midday, one should avoid direct Sun exposure. Consider a wide-brim hat essential for effective sun defense covering your face, neck, and eyes.
