The 2007 Pacific typhoon season had no official bounds; it ran year-round in 2007, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. For the PAGASA, only 13 systems formed or entered in their area during 2007, which only 3 of them directly made landfall over the Philippines.
