Vinh Long, Vietnam

May brings with it the peak of wet season, presenting a stark contrast to the climatic circumstances in Vinh Long during April. Indicators show a spike in rainfall with a transition towards a higher daily average of 38mm (1.5"). The days become shorter due to increasing cloud cover and subsequent reduction in direct sunlight. This weather trend sets a rhythm for June, posing a mixture of a slight temperature drop but continuation of increased rainfall conditions. The overall atmosphere becomes more humid and the wind familiarizes itself with a milder flow.

Metrics for the heat index primarily focus on shaded spots and light wind conditions. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a single figure representing how weather conditions feel when combining temperature and humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Given direct exposure to sunlight, one might experience a rise in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance 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.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.

Guard oneself from overexposure. Defence against sun injury is vital. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly.
