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

The ushering in of September brings an average high-temperature of a tropical 31.5°C (88.7°F), closely mirroring the 29.5°C (85.1°F) of August. Despite the high peak temperatures, Cauo witnesses an average nighttime cooling to a comfortable 18.1°C (64.6°F) in September.

Heat index

The heat index value for September is calculated to be a fiery hot 35°C (95°F). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', gives an indication of how one might feel in terms of heat after considering humidity. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. Heightened relative humidity interferes with the body's usual cooling mechanism by reducing evaporation, subsequently decreasing the body's cooling rate and increasing the sensation of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Humidity

With an average relative humidity of 56%, September is the least humid month.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. The Sun's UV radiation is at its strongest between the hours of 10 a.m. and 4 p.m. Minimize direct exposure to the sun during this period. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
