The climate of the Philippines is largely dominated by two monsoons, the North East or winter and South West or summer. North Eastern winds are blowing between December and May and West Eastern winds during the other months of the year. The trade winds from the West come with heavy rainfall in the Western part of the country and the Eastern winds likewise in the East. Intermediate and Southern parts of the archipelago receive lesser amounts of rain and the rain is more equally distributed through the year. The average annual rainfall in the Philippines ranges from 96 cm / 38 inch to 406 cm / 160 inch.
Each year an average of 9 typhoons hit the Philippines and cause widespread devastation and flooding between July and October, with September being the most active month.The typhoons come in from the Western Pacific ocean and mostly affect the Eastern part of the archipelago with Northern Luzon and the eastern Visayas taking the brunt of the storms. Mindanao is the only region in the Philippines saved from the onslaught of typhoons due to its Southern location.
