Weather in September
Temperature
September experiences an average high-temperature of a still hot 87.6°F (30.9°C), barely different from August's 90.7°F (32.6°C). Howells's September nights cool down to an average low-temperature of 69.4°F (20.8°C).Heat index
The heat index value during September is computed to be a very hot 102.2°F (39°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.It is emphasized that the heat index's values are meant for shaded zones with mild winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The natural method the human body uses to remove excess heat is by perspiring and letting sweat evaporate. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Avoid exposure to the Sun and try to stay in the shade between 10 a.m. and 4 p.m., when UV radiation is most potent, but be aware that parasols or canopies may not offer full protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
