May weather forecast
Bolama, Guinea-Bissau

May marks the turning point of the seasons with rainfall significantly increasing to 7mm (0.28"). This shift ushers in a period of heightened humidity in Bolama, taking the values up from the norm observed in the first quarter of the year. Nonetheless, the change does not bring about consistent rainy days, but rather short-lived showers that quickly yield to the sunny weather. Daylight hours peak during May, allowing more time for daytime activities. Despite the increased rainfall, visibility does not suffer, maintaining optimal conditions for sightseeing trips around Bolama, Guinea-Bissau.

Temperature

Transitioning from April to May, Bolama observes an average high-temperature of a tropical 33.7°C (92.7°F), differing subtly from the previous month. During the month of May, Bolama experiences a steady low-temperature average of 24.4°C (75.9°F).

Heat index

In May, the heat index is evaluated at a blistering 41°C (105.8°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Deter overexposure. Protecting against the sun's effects is essential. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. Employ a wide-brim hat for potent defense against up to 50% of UV rays. Be on guard! The reflective nature of sand and water boosts UV exposure.
