The days are longer too, making it one of the sunniest months of the year. Despite a slight drop in relative humidity from May to June, the noticeable increase in sea temperature coupled with copious rainfall marks the full arrival of the summer season.

Temperature

As June takes hold in Macau, the average high-temperature is a hot 30.3°C (86.5°F), nearly mirroring that of the previous month. During June, Macau's nights hold steady with an average temperature of 25.6°C (78.1°F), barely dropping from the daytime highs.

Heat index

For most parts of June, the heat index is computed to be a scorching 40°C (104°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children are often less aware of the need to rest and re-hydrate. Thirst is a late sign of dehydration - it's vital to remain hydrated, particularly during prolonged physical activities.
When it comes to cooling down, the human body's primary method is through perspiration, making use of sweat evaporation to eliminate excess heat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

Note: In June, a daily UV index of 12 turns into the following recommendations:
Take every essential safety procedure. Individuals with fair skin could sustain burns in less than 5 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure. Even if it's cloudy, generously apply and frequently reapply a sunscreen with no less than a 30 sun protection factor after each swim or outdoor exercise. Note! The Sun's UV radiation gets intensified with the reflection from sand and water.
