March weather forecast
Bolama, Guinea-Bissau

March presents slightly hotter conditions than February, reaching a peak high of 35.5°C (95.9°F). This month signals the start of Bolama's transition period from dry to wet season, with a slight increase in rainfall from the previous months. The change in weather becomes noticeable with a greater humidity index and more cloud cover than in the earlier months. Expect longer daylight hours and a steady sea temperature perfect for cooling off. Despite the increment in rainfall, March still provides predominantly clear skies and reduced wind speeds which favor nearly all types of outdoor activities.

Temperature

March, recognised by an average high temperature of 35.5°C (95.9°F) and a low of 22.8°C (73°F), is Bolama's warmest month.

Heat index

In March, the average heat index is evaluated at a scorching 40°C (104°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
The standards for the heat index are set for locations in shade and under light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', binds temperature metrics with humidity values to give a sense of the actual warmth. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for 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.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.

Humidity

The average relative humidity in March is 44%.

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for ordinary individuals.
Note: A daily high UV index of 7 in March leads to these guidelines:
Steer clear of overexposure. Fair-skinned individuals can be scorched in less than 20 minutes. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage. Note! Reflective surfaces like sand and water heighten the UV radiation levels.
