Taipei, Aug. 26 (CNA) — Average rainfall in Taiwan fell more than 60 percent in July compared to July 2021 and was the lowest for the month since 2008, partly due to no typhoons making landfall on the island , a government report has found.
The report, issued by the Directorate-General for Budget, Accounting and Statistics, says the average monthly rainfall recorded at Central Weather Bureau (CWB) monitoring stations in July was 83 millimeters, down 63.9 percent from that previous year and the lowest value since 2008.
The lack of rain in July contributed to the low rainfall, according to the report.
July and August are usually the peak months for typhoons in Taiwan, but the country has not seen a single typhoon so far this year.
From January to July, the cumulative rainfall of the 27 monitoring stations averaged 1,333 mm, with stations in Su’ao in Yilan County (2,849 mm) and Keelung (2,649 mm) receiving the most, while one in Kaohsiung (603 mm) receiving the lowest was a total of seven months.
Despite relatively high rainfall since January, Keelung has fallen victim to low rainfall in July and is facing water shortages.
The city received just 31mm of rain in July – about a quarter of the monthly average over the past 10 years – leaving its main reservoir, Xinshan (新山水庫), at just 39.5 percent full.
This has forced the Taipei Water Authority to send more than 85,000 cubic meters of water a day to Keelung and prompted the Water Resources Authority (WRA) to issue a water alert for Keelung and Xizhi District in neighboring New Taipei.
However, water remained plentiful in other reservoirs across Taiwan.
The second Baoshan reservoir (100 percent filled) in Hsinchu County, the Yongheshan reservoir (98 percent) and Liyutan reservoir (98 percent) in Miaoli County, the Hushan reservoir (100 percent) in Yunlin County, the Lantan Reservoir (98 percent) in the city of Chiayi and Nanhua Reservoir (100 percent) in Tainan were all almost full and will be able to provide water steadily by the end of this year, the WRA said.
The lack of typhoons also led to higher temperatures in July, with the average temperature at the 27 monitoring stations during the month reaching 27.4 degrees Celsius, 0.3 degrees higher than a year earlier, according to the report.
Taipei had the highest average temperature of 30.8 degrees, and the average temperature at the monitoring station on Jade Mountain, Taiwan’s highest peak at 3,952 meters, reached a record high of 10.1 degrees.
The average temperature from January to July this year across Taiwan was 21.1 degrees, 0.2 degrees lower than the average for the previous decade, the report said.
