July weather forecast
Cổ Loa, Vietnam

July, like June, is another tropical summer month in Cổ Loa, Vietnam, with an average temperature ranging between max 34°C (93.2°F) and min 26.3°C (79.3°F).

Temperature

The onset of July brings with it an average high-temperature of a tropical 34°C (93.2°F), showing a negligible variation from the month before. Nighttime temperature experiences an average drop to a warm 26.3°C (79.3°F) in July.

Heat index

July's heat index is evaluated at a burning hot 50°C (122°F). Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', melds the effects of warmth and moisture to generate a feeling of heat. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

UV index

May through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health risk from exposure to the Sun's UV radiation for average individuals.
Note: The maximum daily UV index, 7 in July, converts into the following recommendations:
Shield from overexposure. Defense against sun-related harm is required. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays.
