April weather forecast
Bula, Guinea-Bissau

April brings a further increase in Bula's temperature and humidity indices. Indeed, the city records up to 50% relative humidity, which combined with temperatures peaking at 35°C (95°F), sets up for a humid atmospheric scenario. The bright day stretches for 12.4 hours, offering ample sunlight for daytime activities. The hike in the wind speed is another distinctive feature setting April apart from the preceding months. Rainfall still remains sparse with the cityscape primarily dominated by the sun’s radiance.

Temperature

As Bula transitions from March to April, the average high-temperatures adjust to a still torrid 35°C (95°F), nearly the same as the previous 35.5°C (95.9°F). During April, Bula observes a consistent average nighttime temperature of 23.5°C (74.3°F).

Heat index

April's average heat index is estimated at a blisteringly hot 41°C (105.8°F). Implement more safety precautions, heat cramps and heat exhaustion may happen. Persistent activity could induce heatstroke.
In terms of the heat index, values are set with light wind and shade conditions in mind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is achieved by amalgamating air temperature with the relative humidity readings. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In April, the average relative humidity is 50%.

Rainfall

In Bula, during April, the rain falls for 2.2 days and regularly aggregates up to 1mm (0.04") of precipitation. Throughout the year, in Bula, Guinea-Bissau, there are 107.5 rainfall days, and 726mm (28.58") of precipitation is accumulated.

UV index

The months with the highest UV index are January through December, with an average maximum UV index of 7. January through December, with an average maximum UV index of 7, are months with the lowest UV index in Bula. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for average individuals.
Note: The maximum UV index of 7 during April leads to these instructions:
Deter overexposure. Protecting against the sun's effects is essential. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
