July weather forecast
Lo Wu, Hong Kong

July, like June, is a hot summer month in Lo Wu, Hong Kong, with an average temperature varying between 31.1°C (88°F) and 27.1°C (80.8°F).

Temperature

The advent of July reveals an average high-temperature of a still tropical 31.1°C (88°F), showing minimal difference from the prior month. Lo Wu in July observes a slight diminution in temperature from daily highs, recording a low-temperature average of 27.1°C (80.8°F).

Heat index

July's mean heat index is computed to be an extremely hot 41°C (105.8°F). Implement enhanced safety actions, heat cramps and heat exhaustion could occur. Sustained activity might result in heatstroke.
Evaluating the heat index requires understanding its values in the shade and with gentle winds. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Guard against overexposure. Protection from sun-induced harm is essential. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. To mitigate harm from sun exposure, pick sunglasses offering UVA and UVB defense.
