May weather forecast
Dự Quần, Vietnam

The last month of the spring, May, is a tropical month in Dự Quần, Vietnam, with an average temperature varying between 25.5°C (77.9°F) and 32.8°C (91°F).

Temperature

The onset of May introduces a subtle rise in the average high-temperature, nudging from a moderately hot 29.1°C (84.4°F) in April to a tropical 32.8°C (91°F). May nights experience a consistent temperature drop to a warm 25.5°C (77.9°F).

Heat index

May's mean heat index is estimated at a blazing hot 45°C (113°F). Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Heat index values can rise by 15 Fahrenheit (8 Celsius) degrees when in direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect is experienced differently by individuals, hinging on unique characteristics such as body mass, stature, and level of activity. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Increased relative humidity slows down evaporation, thereby decreasing the rate of heat removal from the body, culminating in a sensation of overheating. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. 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. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
