2025 Pacific typhoon season

The 2025 Pacific typhoon season was the second consecutive season to have a slightly above-average season in terms of named storms and typhoons. However, it was a below-average season in terms of accumulated cyclone energy (ACE) and super typhoons. Of the twenty-seven named tropical storms, thirteen became typhoons and only one managed to intensify into a super typhoon. Many storms were also weak and short-lived, particularly before and after the peak season activity. The season ran throughout 2025, though most tropical cyclones typically develop between June and November. In addition, the season's first named storm, Wutip, developed on June 11, the fifth-latest date for a typhoon season to produce a named storm, while the season’s last named storm, Koto, dissipated on December 3. In addition, the season’s first typhoon, Danas, reached that intensity on July 6. The scope of this article is limited to the Pacific Ocean north of the equator between 100°E and the 180th meridian. Within the northwestern Pacific Ocean, two separate agencies assign names to tropical cyclones, which can result in a system having two names. The Japan Meteorological Agency (JMA) names a tropical cyclone when it is estimated to have 10-minute sustained winds of at least 65 km/h (40 mph) anywhere in the basin. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that move into or form as a tropical depression within the Philippine Area of Responsibility (PAR), defined as the area between 135°E–115°E and 5°N–25°N, regardless of whether the JMA has already named the system. Tropical depressions monitored by the United States Joint Typhoon Warning Center (JTWC) are given a numerical designation with a "W" suffix, which means "west", a reference to the western Pacific region.
