Dục Nội, Vietnam

July, the same as June, in Dục Nội, Vietnam, is another tropical summer month, with an average temperature varying between 26.3°C (79.3°F) and 34°C (93.2°F).

Temperature

The start of July sees the average high-temperature at a tropical 34°C (93.2°F), showing little difference from June's 35.4°C (95.7°F). July is noted for a mean low-temperature of 26.3°C (79.3°F).

Heat index

July's heat index is estimated at a blazing hot 50°C (122°F). Beware: Heat cramps and heat exhaustion are very likely. Heatstroke is imminent with prolonged activity.
Realize that the values for the heat index are set for shaded places and light winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
