Zambales Islands Philippines
"Zambales Geography"

Climate
Zambales has two pronounced seasons: dry from October to June, and wet from July to September.

Physical
Zambales lies on the western shores of Luzon island, between the Zambales Mountains and the South China Sea. Its shoreline is very ragged, and features many coves and inlets. The mountain range on the eastern part of the province occupies about 60% of its total land area. Subic Bay, in the southernmost part of the province, provides a natural harbor, and was chosen as the location of an American naval base. The peak of Mount Pinatubo lies on the intersection of the boundaries between Zambales, Pampanga, and Tarlac. This volcano, once considered dormant, erupted violently in 1991.

Political
Zambales is subdivided into 13 municipalities and 1 city. Olongapo City is a highly urbanized city and administers itself autonomously from the province. Panatag Shoal (Scarborough Shoal) a Philippine-claimed EEZ, is a designated part of the province.
