Weather in September
Temperature
September's onset sees an average high-temperature of a torrid 35.7°C (96.3°F), exhibiting a slight fluctuation from the previous month. Ardebe's temperature in September lowers to a consistent average of 25.9°C (78.6°F) during the nights.Heat index
In September, the average heat index is evaluated at a blazing hot 45°C (113°F). On guard: Heat exhaustion and heat cramps are predicted. Heatstroke is a potential hazard with continuous physical effort.In terms of the heat index, values are set with light wind and shade conditions in mind. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', reflects the feeling of heat when considering both air temperature and humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Always be mindful of protection. The risk of damage to skin and eyes is significant if neglected. Be aware that the sun's UV radiation is strongest between 10 a.m. and 4 p.m. and try to reduce direct sun exposure during this period as much as possible. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
