Hanoi reaches its highest average temperatures in June, measuring 35.4°C (95.7°F) at the peak and 26.6°C (79.9°F) at the lowest.

Heat index

During June, the heat index is estimated at a life-threatening hot 52°C (125.6°F). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
Heat index determinations are made taking into account the shade and light air movements. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
