Temperature

The arrival of July marks a slight shift to an average high-temperature of a still hot 30.6°C (87.1°F) from June's 31.6°C (88.9°F). Lao Cai experiences a mean temperature of 20.6°C (69.1°F) during July nights.

Heat index

The heat index value during July is estimated at a very hot 39°C (102.2°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. 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. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
