Taipei: Taiwan may experience one or two typhoons this fall, alongside higher-than-average temperatures and rainfall, as reported by the Central Weather Administration (CWA) on Friday. While the number of expected typhoons aligns with historical averages, these weather events are anticipated to form closer to Taiwan, potentially leading to increased rainfall in conjunction with seasonal northeasterly winds, according to Huang Chun-hsi, deputy director of the CWA's Weather Forecast Center.

According to Focus Taiwan, the prediction is informed by historical data associated with La Ni±a weather patterns. The bureau anticipates the development of La Ni±a by fall, attributed to cooler Eastern Pacific sea temperatures, as explained by Huang. Based on historical trends, autumn typhoons typically move west or northwest. Despite these projections, central and southern Taiwan may still face dry conditions in the fall, prompting public advisories to conserve water and stay updated with the CWA's weekly and monthly forecasts.

Reflecting on the summer of 2025, the season was characterized by "more rainfall, less sunshine, and slightly lower temperatures," Huang noted. In July, a combination of five typhoons, low-pressure systems, and southwest currents resulted in "prolonged heavy rainfall," with an average of 767 millimeters nationwide - the highest for July since 1951, the CWA reported.

Consequently, only 333.4 hours of sunshine were recorded in July and August, marking the second lowest since 1951, based on CWA data. The average temperature during these two months was 28.6 degrees Celsius, just 0.2 degrees below the 1991-2020 average, indicating the ongoing impact of global warming on Taiwan's climate.

Additionally, seven typhoons formed in July, ranking as the third-highest number since 1958, the administration revealed.
