This timeline documents all of the events of the 2015 Pacific typhoon season. Most of the tropical cyclones forming between May and November. The scope of this article is limited to the Pacific Ocean, north of the equator between 100°E and the International Date Line. Tropical storms that form in the entire Western Pacific basin are assigned a name by the Japan Meteorological Agency. Tropical depressions that form in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center. In addition, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones (including tropical depressions) that enter or form in the Philippine area of responsibility. These names, however, are not in common use outside of the Philippines.

During the season, 7 systems were designated as Tropical Depressions by either, the Japan Meteorological Agency (JMA), the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the Joint Typhoon Warning Center (JTWC), or other National Meteorological and Hydrological Services such as the China Meteorological Administration and the Hong Kong Observatory. As they run the Regional Specialized Meteorological Centre for the Western Pacific, the JMA assigns names to Tropical Depressions should they intensify into a tropical storm. PAGASA also assign local names to tropical depressions which form within their area of responsibility; however, these names are not in common use outside of PAGASA’s area of responsibility. In this season, 3 systems entered or formed in the Philippine area of responsibility, which two of them directly made landfall over the Philippines.

The first three months of the season were unusually active and intense. Mekkhala became an early-forming storm of the season and affected the Philippines. Whilst Higos, which formed a month after Mekkhala, reached its peak intensity as a Category 4 typhoon and broke the record of the most intense storm and the easternmost forming storm within the basin during the month of February. During the end of next month, Typhoon Maysak reached its peak intensity as a Category 5 super typhoon with a minimum pressure of 905 millibars, which became the strongest typhoon before the month of April.

Season summary

2015 opened with Tropical Depression Jangmi (Seniang) located about 145 km (90 mi) to the northeast of Sandakan, Malaysia. The system subsequently moved south-eastwards and made landfall on Malaysia before dissipating later that day. A tropical depression subsequently developed to the northwest of Brunei during January 2, but did not develop any further and dissipated during January 4. The first tropical storm of the season was named Mekkhala during January 14 and went on to affect the Philippines and Pope Francis' visit to the Philippines. Less than a month later, Typhoon Higos had become the easternmost forming Pacific typhoon as well as being among the strongest February typhoons of record. Despite its intensity, Higos did not cause any significant effects over the landmasses and islands on the West Pacific. During the end of March, Typhoon Maysak formed and intensified into a Category 5 super typhoon, the strongest so far in the season and among the strongest prior to April.
