It was a very active season, including a 924 hPa cyclone. The last system of this system is former Typhoon Surigae, with the lowest central pressure of former tropical cyclones among the whole lists of this page.

From September 2001 to August 2024, the Japan Meteorological Agency reported 115 extratropical cyclones with typhoon-equivalent (10-minute) maximum sustained winds in the Northwest Pacific Ocean. There was an average of 5 systems reaching that intensity each period.

About three fourths of typhoon-equivalent extratropical cyclones were at 65 knots. Approximately one 70-knot system formed each period. Systems at or over 75 knots were extremely rare.

Unlike tropical cyclones, the central pressure of typhoon-equivalent extratropical cyclones at the same or similar intensity could vary significantly, although more than a half of total systems were between 950 to 970 hPa. The highest one was 988 hPa recorded in December 2012, while the lowest one was 920 hPa recorded in November 2014.

More than a half of total systems formed between December and February. Lots of September and October systems were originally tropical. No typhoon-equivalent systems were recorded in May, July and August.
