May weather forecast
Barro, Guinea-Bissau

The last month of the spring, May, is another extremely hot month in Barro, Guinea-Bissau, with an average temperature fluctuating between 40.5°C (104.9°F) and 24.1°C (75.4°F).

Temperature

Barro's weather, upon May's arrival, documents an average high-temperature of a still blisteringly hot 40.5°C (104.9°F), nearly identical to the prior month. Nighttime temperatures throughout May register a significant deviation from the day's highs, averaging at a warm 24.1°C (75.4°F).

Heat index

In May, the average heat index is computed to be a blazing hot 52°C (125.6°F). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.
The metrics for the heat index are tailored for both shady environments and light winds. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', is an aggregate value of air's warmth and moisture to show the human-felt temperature. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 are especially vital to children. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. 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 the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Humidity

In May, the average relative humidity is 44%.

Rainfall

In Barro, during May, the rain falls for 3.3 days and regularly aggregates up to 4mm (0.16") of precipitation. In Barro, during the entire year, the rain falls for 109.1 days and collects up to 654mm (25.75") of precipitation.

Daylight

In May, the average length of the day is 12h and 42min.
On the first day of the month, sunrise is at 06:42 and sunset at 19:16. On the last day of May, sunrise is at 06:36 and sunset at 19:24 GMT.

Sunshine

The average sunshine in May is 9.8h.

UV index

The months with the highest UV index are March through May, with an average maximum UV index of 8. A UV Index reading of 8 to 10 represents a very high health vulnerability from exposure to the Sun's UV radiation for the average person.
Note: A daily maximum UV index of 8 in May translates into the following instructions:
Take all necessary measures. Eyes and skin are at risk if left unprotected. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage.
