August weather forecast
Macau, China

Continuing the summer's sizzling saga, August remains one of the hottest months in Macau, China. With a slight drop in temperature from July to August but maintaining a high rainfall, the climate can feel rather humid and sultry. Swimming continues to be a favorite pastime with sea temperatures reaching significant highs. The outdoor weather beckons with clear skies and ample sunshine during daylight hours.

Temperature

The arrival of August sees a recorded average high-temperature of a still hot 31.5°C (88.7°F), showing little divergence from the previous month's conditions. Macau throughout August, records an average low-temperature of 26.1°C (79°F).

Heat index

In August, the average heat index is computed to be a blisteringly hot 43°C (109.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.
Heat index's context suggests values are appropriate for shady areas and slight breezes. With exposure to direct sunshine, the heat index could climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', combines air temperature and relative humidity to represent a human perceived temperature equivalent. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Humidity

In August, the average relative humidity is 81.4%.

Rainfall

Note: A daily high UV index of 12 in August leads to these guidelines:
Adopt every precaution of necessity, unprotected skin and eyes may suffer burns instantly. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. Sun-related eye harm can be minimized with proper sunglasses offering UVA and UVB coverage. Use liberally and reapply a broad-spectrum sunscreen with at least SPF 30 every two hours and right after outdoor activities or a swim. Heads up! UV intensity is amplified by reflections from water and sand.
