May weather forecast
Bồng Sơn, Vietnam

As summer sets in firmly, May in Bồng Sơn presents the warmest temperatures of the year, reaching a blazing 31.9°C (89.4°F) during the day. Despite this, the abundant sunshine of 11.5 hours and the longest daylight hours of 12.8 hours make this month a perfect time for sun worshipers. Winds undergo a transformation, shifting from Southeast to South, reflecting dominant monsoon patterns. Albeit a high-pressure month, May exhibits a slight upswing in the rainfall at 39mm (1.54"), but with these showers dotting barely half the month, the dry hot spell continues to rule.

Temperature

May and June, with an average high-temperature of 31.9°C (89.4°F), are marked as the warmest months.

Heat index

May's heat index is estimated at a blisteringly hot 43°C (109.4°F). Be alert: Heat exhaustion along with heat cramps are probable. Heatstroke is a threat with sustained physical activity.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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 normally cools itself by perspiration, as evaporated sweat carries heat away from the body. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
