Weather in September
Temperature
September brings an average high-temperature of a still hot 86.7°F (30.4°C), nearly identical to the preceding month. The average temperature during September nights is registered at a refreshing 66.4°F (19.1°C).Heat index
For September, the heat index is computed to be a very hot 98.6°F (37°C). Take additional safety steps, risk of heat exhaustion and heat cramps is notable. Prolonged activity may cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'feels like' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids frequently ignore the importance of taking a break and rehydrating. Thirst is a late symptom of dehydration - thus, it is crucial to stay hydrated, especially during long-lasting physical activities.
The human body cools itself through perspiration, as excessive warmth is removed from the body through 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. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
