September weather forecast
Cauo, Mozambique

September marks the end of the dry season in Caia, giving way to the start of rains, albeit only a slight increase to 2mm (0.08") from the negligible August rainfall. A noticeable rise in temperature combined with a steady increase in relative humidity turns up the tropical feel in the city. The strong sun coupled with bright blue skies commands a picturesque view, while occasional clouds and light breezes provide occasional relief from the heat. It's a striking transition period as the city prepares to welcome the rainy season once again.

Temperature

September's weather displays an average high-temperature of a hot 31.5°C (88.7°F), slightly varied from August's 29.5°C (85.1°F). From the height of daytime heat, the temperature recedes to an average of 18.1°C (64.6°F) at night during September.

Heat index

In September, the heat index is computed to be a sweltering 35°C (95°F). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.
One should be cognizant that the heat index values are tailored for shaded spots and mild winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a single figure representing how weather conditions feel when combining temperature and humidity. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary 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. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
