November weather forecast
Mansaba, Guinea-Bissau

Coming to November, Mansaba welcomes a significant change as it marks the beginning of the dry season with the desert winds - known as harmattan - taking over. The city is swept by a dry and dusty breeze, reducing the rainfall to a low 2mm (0.08"). The landscape alters with the end of the monsoon, replaced by dusty terrains under the clear skies. November sets the precedent for December, the driest month of the year.

Temperature

As Mansaba transitions into November, the average high-temperature stands at a torrid 36°C (96.8°F), offering little variation from the preceding month. Mansaba experiences a dramatic descent in temperature during November, with the average nighttime reading settling at an agreeable 21.6°C (70.9°F).

Heat index

In November, the heat index is appraised at a scorching 42°C (107.6°F). More safety actions are required, heat exhaustion and heat cramps are probable. Long-term activity may precipitate heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a numerical representation of warmth when taking temperature and moisture levels into account. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. 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 highly critical to babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Humidity

In November, the average relative humidity is 48%.

Rainfall

November is the last month it rains. During 1.7 rainfall days, in November, Mansaba aggregates 2mm (0.08") of precipitation. Throughout the year, there are 107.6 rainfall days, and 593mm (23.35") of precipitation is accumulated.

UV index

In November, the average daily maximum UV index is 7. A UV Index estimate of 6 to 7 represents a high threat to health from exposure to the Sun's UV rays for ordinary individuals.
Note: The daily high UV index of 7 during November translates into the following recommendations:
Avoid excessive sunlight. Those with lighter skin may experience burning in less than 20 minutes. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Wearing sunglasses with both UVA and UVB protection effectively reduces sun-induced eye damage.
