In September, Matundo’s weather begins to return to its warmer and wetter characteristics. Preluding the rainy season’s onset, atmospherical pressure tends to drop and cloud coverage sees an incremental increase. However, this month remains largely dry, with only 1mm (0.04") of rainfall recorded. Winds in September provide a refreshing change, with their speeds escalating to an average of 10.7km/h (6.6mph). The September sun shines a bit longer, averaging 9.5 hours of sunshine daily.

Temperature

A slight uplift of average high-temperatures is noted in September, with temperatures adjusting from 30.4°C (86.7°F) in August to a still tropical 34.3°C (93.7°F). Matundo's average low-temperature of 20.5°C (68.9°F) in September reflects a considerable decline from the daytime peak.

Heat index

The heat index in September is evaluated at a torrid 36°C (96.8°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.
Heat index evaluations are typically in the context of light winds and shaded environments. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.

Endorse precautions and be consistent with sun safety guidelines. Preventing sunburn is paramount. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
