Weather in May
Temperature
As May starts, an average high temperature of a still moderately hot 29.3°C (84.7°F) suggests no significant change from April. In the month of May, Buna witnesses a consistent average low-temperature of 21.8°C (71.2°F).Heat index
The heat index for May is computed to be a sweltering 35°C (95°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'feels like', is an estimation of the warmth sensation when considering humidity levels. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The human body has a built-in cooling mechanism through perspiration; evaporating sweat dissipates the excess heat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

February through October and December, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index reading of 6 to 7 represents a high health vulnerability from unprotected exposure to Sun's UV rays for the ordinary person.Note: A daily maximum UV index of 6 in May translates into the following instructions:
Continue precautions and advocate sun safety advice. Deterrence of sunburn is indispensable. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Experience reduced UV exposure by about half when donning a wide-brim hat.
