\section{Introduction}  Wildfires are a global problem that produces severe impacts. Catastrophic wildfire events claim lives, degrade the environment and destroy building infrastructure. Eventhough wildfires are a natural part of the evolution of natural ecosystems, population growth and its influence over nature exerts great influence over this phenomena. In fact, most wildfires have an anthropogenic ignition pattern. Additionally, people massively lose their lives in wildfire events because urban expansion over wildfire-prone areas increases their vulnerability to this hazard. These actions amplify the impact over people, nature and infrastructure. Wildfires also degrade the soil, pollute air and water, contribute to biodiversity loss, and affect the climate. Furthere, the economic impact of these events produces billions of dollars in losses each year. The relevance of this problem have encouraged extensive research on the behavior of its precursors.   The climate system is one of the key components that contributes to wildfire activity. The interaction and evolution of this system determines the response of meteorological variables that have direct influence over wildfires. Common variables associated with wildfire occurrences are temperature, relative humidity, wind speed and precipitation. The relationship between this variables and the wildfire-prone ecosystems is complex. However, each variable ultimately affects the availability of fuels to be burnt through Evapotranspiration.  Reasearch conducted in several regions of the world have demonstrated a link between ENSO and fire activity \cite{Swetnam1983,Simard1985a,Kitzberger2002,Beckage2003,Carmona-Moreno2005,Nicholls2007a,Wooster2012, Harris2013}. The relationship is usually associated with a particular ENSO phase (El Niño or La Niña) and negative rainfall anomalies. These anomalies depend on the regional impact of ENSO over climate and are reflected in the rainfall deficits over the months before —and during– the wildfire season. This influence could be exacerbated if, for example, a strong El Nino event is in superposition with a negative Interdecadal Pacific Oscillation (IPO) phase \cite{A2004}. ENSO may even have an influence over ignition patterns, fostering the occurrence of lightning strikes \cite{Beckage2003}. This encourages the investigation of new studies of ENSO-related wildfire danger variability and predictability in other regions in the world.
