Weather in May

Temperature

As Nội Cốc welcomes May, the average high-temperature displays a subtle shift, adjusting from a warm 29.5°C (85.1°F) in April to a tropical 33°C (91.4°F). In the month of May, the temperature generally rests at an average low of 25.3°C (77.5°F).

Heat index

The heat index value during May is evaluated at a life-threatening hot 46°C (114.8°F). Stay vigilant: Heat cramps along with heat exhaustion are expected. Heatstroke may follow prolonged exertion.
Be aware that heat index ratings are designed for shaded locations and minor breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The primary way humans combat excessive warmth is by perspiring, letting sweat evaporate and cool the body. Augmented relative humidity impedes typical body cooling mechanisms by lowering the evaporation rate, resulting in decreased body cooling and an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
