May weather forecast
Canuau, Guinea-Bissau

The last month of the spring, May, is another very hot month in Canuau, Guinea-Bissau, with an average temperature varying between 35.3°C (95.5°F) and 23.8°C (74.8°F).

Temperature

Canuau experiences an average high-temperature of a still torrid 35.3°C (95.5°F) in May, subtly different from April's 36.7°C (98.1°F). May nights in Canuau cool down to an average low-temperature of 23.8°C (74.8°F).

Heat index

For May, the heat index is calculated to be a scorching 44°C (111.2°F). Take heed: Heat exhaustion and heat cramps are anticipated. Heatstroke is a potential outcome of continuous activity.
Heat index values are typically calculated for conditions of shade and a light breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. 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. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Humidity

The average relative humidity in May is 56%.

Rainfall

In Canuau, in May, it is raining for 4 days, with typically 11mm (0.43") of accumulated precipitation. Throughout the year, there are 103.1 rainfall days, and 677mm (26.65") of precipitation is accumulated.

UV index

January through June, September through December, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.
Note: The maximum daily UV index, 7 in May, converts into the following recommendations:
Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Stay sun-safe with clothing that is both closely woven and worn loosely.
