Trends of extreme daily rainfall frequency in the Philippines (1951–2010) compared with the 1961–1990 mean value. et al., 2013). The station at Baguio shows a decreasing trend in SWM rainfall, a significant increase in no rain days as well as an inter-decadal reduction in heavy rainfall days above the 95th percentile. Conversely, our results show a significant increase in rainfall intensity and an insignificant increase in frequency of extreme rainfall. Baguio is situated in a mountainous region of the Philippines and in addition to orographic influences, is subject to visiting tropical cyclones. It is also located in a region which was found to exhibit anomalous rainfall signals associated with early development (JAS) El Niño (La Niña) phases which normally bring drier (wetter) conditions (Lyon and Camargo, 2008; Villafuerte et al., 2014) to the north central Philippines. The station at Iloilo shows an increase in SWM rainfall, albeit minimally, as well as a slight increase in inter-decadal heavy rainfall. There was also a significantly increasing trend in 5 day maximum rainfall found at this station for the same period (1951– 2010) in a recent study by Villafuerte et al. (2014). This study also confirmed the influence of ENSO events on the seasonal rainfall patterns of the Philippines and provides perhaps the strongest evidence yet at a national level, of its influence on extreme rainfall indicators. Taken together this would
