Macau’s mean air temperature last year was 23.6 degrees Celsius, which was 0.8 ºC above the climatological normal, i.e., the average value for 1991-2020, the Statistics and Census Bureau (DSEC) announced in a statement yesterday.
According to the statement, last year’s highest temperature was 35.4 ºC in August. There were 42 very hot days (with the maximum temperature at or above 33 ºC) and 29 hot nights (with the minimum temperature at or above 28 ºC), representing respective increases of 10.7 days and 17.5 nights when compared to the climatological normal.
On the other hand, the number of cold days (with the minimum temperature at or below 12 ºC) decreased by 10.1 to 29 days as compared to the climatological normal.
Macau’s rubbish incinerator in Pac On district treated a total of 526,979 tonnes of municipal solid waste in 2024, up by 5.1 percent year-on-year. Per-capita municipal solid waste rose from 2.02 kg per day in 2023 to 2.10 kg. Meanwhile, the amount of construction waste sent to Macau’s landfill grew by 13.5 percent to 1,803,000 m3, while the amount of special and hazardous waste dipped by 0.9 percent year-on-year to 5,355 tonnes.
Water consumption rose by 5.6 percent year-on-year to 94,123,000 m3 last year. The increase was mainly attributed to the growth in water consumption by the government sector (+12.0 percent) and the industrial and commercial sectors (+8.5 percent), which raised per-capita water consumption from 359.9 litres per day in 2023 to 374.3 litres. Besides, a total of 87,532,000 m3 of waste water was treated, up by 4.5 percent year-on-year.
The air quality ranged from “good” to “very bad” in 2024. Compared with 2023, the number of days with “bad” or “very bad” air quality increased. Among all monitoring stations, the Ka-Ho Roadside station had the highest number of “bad” air quality days (34) and recorded two “very bad” air quality days. This station also registered the highest air quality index of the year, at 216 (“very bad” level), with ozone (O3) being the main pollutant.
Macau’s land area remained at 33.3 km2, while the population density increased 0.98 percent from 20,400 individuals per km2 in 2023 to 20,600 individuals last year, one of the world’s highest.
