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

May's beginning signals an average high-temperature of a still tropical 30.2°C (86.4°F), barely different from April's 30.6°C (87.1°F). Boffa maintains a near steady average temperature of 25.4°C (77.7°F) during the nights of May, demonstrating little drop from daytime highs.

Heat index

The heat index value during May is computed to be a sweltering 37°C (98.6°F). Heightened precautions are necessary, heat cramps and heat exhaustion are potential risks. Continuous activity could lead to heatstroke.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'feels like' or 'felt air temperature', gives a temperature feeling by integrating air temperature and humidity. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
Perspiration and the resultant sweat evaporation are the body's natural thermostat, helping regulate temperature. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Humidity

The average relative humidity in May is 77%.

Note: A maximum UV index of 7 in May translates into the following recommendations:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Stay alert! Reflective properties of sand and water amplify the Sun's UV radiation.
