Weather in September
Temperature
Arbo's shift into September sets the average high-temperature at a still hot 87.4°F (30.8°C), a figure that deviates only slightly from August's 91.4°F (33°C). Throughout the month of September, Arbo observes an average nighttime temperature of 67.8°F (19.9°C).Heat index
September's average heat index is evaluated at a fiery hot 102.2°F (39°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.For clarity, heat index numbers account for light winds and areas under shade. 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 'felt air temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.
