Ribaue, Mozambique

September, the first month of the spring in Ribaue, is a hot month, with temperature in the range of an average high of 31.3°C (88.3°F) and an average low of 17.9°C (64.2°F).

Temperature

The onset of September brings an average high-temperature of a tropical 31.3°C (88.3°F), nearly matching the August temperature. Ribaue encounters a substantial decline from its daily high to a low-temperature of 17.9°C (64.2°F) during September nights.

Heat index

September's average heat index is evaluated at a sweltering 36°C (96.8°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.
It is important to note that the heat index values are for shaded areas and light wind scenarios. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As the body accumulates more heat than it can release, body temperature goes up, increasing the risk of heat-related health issues.

Humidity

The average relative humidity in September is 61%.

Rainfall

The month with the least rainfall is September, when the rain falls for 3.3 days and typically collects 3mm (0.12") of precipitation.

UV index

September through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: The maximum daily UV index, 7 in September, converts into the following recommendations:
Enforce precautions and stick to sun safety measures. Preservation from skin and eye damage is essential. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
