Weather in September
Temperature
As August transitions into September, Josephine sees a gentle drop in the average high-temperature, transitioning from a torrid 95°F (35°C) to a hot 87.1°F (30.6°C). An average nighttime temperature of 68.7°F (20.4°C) is witnessed throughout September.Heat index
In September, the average heat index is appraised at a fiery hot 95°F (35°C). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.Heat index evaluations are typically in the context of light winds and shaded environments. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a composite of temperature and humidity figures to convey how warm it feels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
