May weather forecast
Brandao, Guinea-Bissau

The last month of the spring, May, is another torrid month in Brandao, Guinea-Bissau, with temperature in the range of an average high of 37.6°C (99.7°F) and an average low of 23.2°C (73.8°F).

Temperature

On the advent of May, Brandao's average high-temperature exhibits a minor adjustment to a still fiery hot 37.6°C (99.7°F) from April's 39.5°C (103.1°F). May nights bring a significant cooling from the heat of the day, with averages of 23.2°C (73.8°F).

Heat index

The heat index value for May is computed to be a blazing hot 53°C (127.4°F). Be cautious: Heat exhaustion along with heat cramps are predicted. Heatstroke is a possible consequence of continuous physical effort.
Heat index values are typically calculated for conditions of shade and a light breeze. Direct sunlight exposure may result in a rise of the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', arises from combining readings of air temperature and relative moisture content. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Note: An average maximum UV index of 7 in May leads to these recommendations:
Shun overexposure. Protection from sun ravages is indispensable. 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. Opt for tightly woven and loose clothing to enhance protection from the Sun.
