The 2005 Pacific typhoon season has no official bounds; it runs year-round in 2005, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.
For the PAGASA, 17 systems formed or entered in their area during 2005, which 7 of them directly made landfall over the Philippines.
No named storms formed in February.
