May weather forecast
Da Nang, Vietnam

May is an invitation to summer in Da Nang, Vietnam. With long days filled with sunshine, the warmth becomes more pronounced, encouraging residents and visitors to seek out the city's beaches. Despite the heat, the weather remains appealing for outdoor activities. May distinguishes itself as the first month with daytime temperatures soaring above 30°C (86°F), recording a high of 31.3°C (88.3°F). As the city progresses into June, the culmination of heat and humidity synergizes into the peak summer months.

Temperature

With the onset of May, the average high-temperature stands at a tropical 31.3°C (88.3°F), closely aligned with April's 29.2°C (84.6°F). During the month of May, an average temperature of 25°C (77°F) is noted during the nights.

Heat index

The heat index for May is computed to be a blisteringly hot 42°C (107.6°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.
Metrics for the heat index primarily focus on shaded spots and light wind conditions. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Note: The daily high UV index of 7 in May translates into this advice:
Ward off overexposure. Defence against solar harm is crucial. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. It's wise to wear UVA and UVB-blocking sunglasses when the sun shines brightly. Stay aware! UV radiation is magnified when reflecting off sand and water.
