Sitting astride the typhoon belt, the islands experience 15–20 typhoons annually from July to October, with around nineteen typhoons entering the Philippine area of responsibility in a typical year and eight or nine making landfall. Historically typhoons were sometimes referred to as "baguios". The wettest recorded typhoon to hit the Philippines dropped in Baguio from July 14 to 18, 1911. The Philippines is highly exposed to climate change and is among the world's ten countries that are most vulnerable to climate change risks.
