Temperature

With the transition into May, Ô Mễ experiences a subtle uplift in average high-temperatures, adjusting from a moderately hot 28.3°C (82.9°F) in April to a tropical 32°C (89.6°F). An average low-temperature of 25.8°C (78.4°F) is recorded during the nights in May.

Heat index

For May, the heat index is evaluated at a blistering 43°C (109.4°F). Be wary: Heat exhaustion and heat cramps are highly anticipated. With continued activity, heatstroke is very likely.
For clarity, heat index numbers account for light winds and areas under shade. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index value of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV radiation for ordinary individuals.
Note: The daily maximum UV index of 7 in May interprets into the following advice:
Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
