May weather forecast
Boffa, Guinea

May marks a dramatic shift in Boffa's weather. The city braces itself for the peak monsoon with a record rainfall of 48mm (1.89"), marking the beginning of the heaviest rainy period throughout the year. The accompanying overcast sky reduces the number of sunshine hours and the increasing daytime temperatures characterize May. Despite the rise in humidity, the breezy weather conditions, and constant sea temperatures, offer a refreshing solace to the residents. The accelerated rain showers and higher temperatures come together to shape the unique tropical monsoon climate of Boffa in May.

Temperature

With the transition into May, Boffa notes an average high-temperature of a still tropical 30.2°C (86.4°F), closely resembling April. Boffa's nighttime temperatures in May settle close to daytime highs at an average of 25.4°C (77.7°F).

Heat index

In May, the heat index is calculated to be a sweltering 37°C (98.6°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Elements such as metabolic variations, pregnancy, and physical exertion can influence one's weather perception. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

Humidity

In May, the average relative humidity is 77%.

Deter overexposure. Protecting against the sun's effects is essential. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage. Attention! UV strength is notably upped by the reflection of sand and water.
