Weather in September
September sees Tiassalé receiving rainfall matching June’s figures at 128mm (5.04"), rising from the preceding month. This is yet another jewel in the crown of the rainy season, which leaves no clear skies, heavy rain showers being an all too familiar scene. However, life in the city never grinds to a halt, with the impeccable civic amenities coping efficiently in dispelling the fears associated with heavy rainfall. Marked by increased cloud cover and high humidity, the weather pattern seems consistent with the preceding months. Despite the wind speed decreasing to 5.4km/h (3.4mph), it takes an active role in dissipating the tropical heat wrapping around the City of Tiassalé.Temperature
In September, Tiassale notes an average high-temperature of a still warm 28.9°C (84°F), hardly different from the preceding month. Tiassale's nighttime temperature in September drops to an average of 21.5°C (70.7°F).Heat index
The heat index for September is calculated to be a sweltering 37°C (98.6°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly important for children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
