May weather forecast
Mandiana, Guinea

The transition towards the rainy season is more evident in May. Despite temperatures remaining high, the weather changes significantly with the onset of the wet season. Humidity levels continue to rise, reaching a substantial 59% relative humidity. As rainfall dramatically increases to 65mm (2.56"), wind levels remain largely unchanged from previous months. Plan for potential changes in outdoor plans due to frequent rainfall, especially towards the end of the month.

Temperature

The arrival of May coincides with an average high-temperature of a still torrid 36.9°C (98.4°F), indicating a minimal shift from April's 39.3°C (102.7°F). Mandiana records a marked divergence from the day's high temperatures, with nights in May averaging at a warm 24.1°C (75.4°F).

Heat index

May's mean heat index is computed to be a blazing hot 50°C (122°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Understand that the heat index values take into account shaded locations and mild winds. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. 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 extremely significant for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Stay out of direct sunlight and seek shade between 10 a.m. and 4 p.m., when UV radiation is strongest, but remember that shade devices may not offer full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
