The province of Pampanga is a part of the great plain extending from Manila Bay north of the gulf of Lingayen, Pangasinan. Most of this area is only a few meters above sea level. Mt. Arayat, with a height of 3,200 ft. and the elevated strip along the western boundary of the Zambales Mountain rise to a height of nearly 1,900 meters constitute the only highland. The general slope is south and southeast towards Manila Bay and Rio Grande. In the northwestern part of the province, however, the land slope is going downward towards Mt. Arayat. Not far from the base is the Pampanga River which channels floodwaters into the wide Candaba Swamp, then to tributaries, rivulets, creeks and finally to Manila Bay.

Only cyclonic or summer rainfall prevail the northeast monsoon rains being hardly noticeable, hence the long dry season. July, August and September are the months of high precipitation while March, April and May are the dry and hot months. The heaviest rains come during the month of July and sometimes last up to October. The heavy rainfalls bring about disastrous floods in some areas like San Luis, San Simon, Lubao, Bacolor, Guagua, Sto. Tomas, Minalin and Apalit.
