The start of May is characterized by a subtle increase in the average high-temperature, transitioning from 30.8°C (87.4°F) in April to a still hot 34°C (93.2°F). Lễ Pháp's average low-temperature during May nights is observed to be a moderately hot 24.8°C (76.6°F).

Heat index

May's average heat index is estimated at a life-threatening hot 49°C (120.2°F). Be prepared: Heat cramps and heat exhaustion are probable. Continued activity may lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Inhibit overexposure. Warding off sun damage is of utmost importance. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
