April weather forecast
Bolama, Guinea-Bissau

The heat in Bolama, Guinea-Bissau intensifies further to reach 35°C (95°F) in April. It is a period of balanced weather, not as dry as the preceding months but not as rainy as the months forthcoming. Slightly cooler sea temperatures provide a welcome contrast to the abundant sunshine that contributes to the warmer climate. Also notable is the increased humidity and cloud cover resulting from the short-lived rain showers. However, these changes do not deter outdoor activities, with plenty of sunshine still available during daylight hours.

Temperature

In April, Bolama experiences a minor shift in meteorological conditions with average high-temperatures marked at a still torrid 35°C (95°F), closely mirroring the climate in March. The average temperature during April nights is registered at a moderately hot 23.5°C (74.3°F).

Heat index

The heat index in April is evaluated at a scorching 41°C (105.8°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', shows a temperature sensation when both heat and moisture conditions are combined. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Younglings frequently fail to recognize the requirement to rest and rehydrate. Thirst emerges late in dehydration - it is imperative to keep hydration levels high, particularly during extended physical exertions.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Humidity

In Bolama, the average relative humidity in April is 50%.

Note: In April, a regular UV index of 7 translates into these guidelines:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes. Warning! The Sun's UV rays intensify with reflections from sand and water.
