May weather forecast
Ntoum, Gabon

May brings a notable shift in weather conditions when compared to the preceding month of April. The fall in temperature, reduced sunshine hours, and an increase in cloud cover may be indicative of the onset of a cooler period within the year. The wind speed rises this month, creating a more breezy ambiance. Despite the cooler environment, the consistency in daylight hours and UV index remains. May is marked by a decline in rainfall to 156mm (6.14"), signaling the end of the primarily wet first quarter of the year.

Temperature

May's advent notes a subtle adjustment in average high-temperature to a still moderately hot 28.9°C (84°F) from April. In Ntoum, a slight decrease from the daytime peak is noted during the month of May, with an average low-temperature of 24.7°C (76.5°F).

Heat index

The heat index value for May is computed to be a torrid 36°C (96.8°F). Incorporate additional safety actions, heat cramps and heat exhaustion are possible. Long-term activity may induce heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. 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 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. Higher relative humidity impedes evaporation, thus reducing heat dispersion from the body, culminating in a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. 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. For excellent sun protection for the eyes, ears, face, and neck, consider a wide-brim hat.
