Grazalema mountain range constitutes a rainfall singularity in the entire national territory. It is located halfway between the provinces of Cádiz and Málaga, with altitudes up to 1600 meters, in an environment of great beauty and natural wealth, where the orographic enhancement of precipitation plays a key role in the rainfall totals amounts. This study shows a brief review of the main climatological features of Grazalema, based on the information available in the AEMET National Climatological Database. Next, we intend to carry out a brief analysis of what the typical meteorological situations are like that enable episodes in which several hundred liters are measured in 24 hours, and that can sometimes reach 1000 liters weekly. Also, a brief review of recent study cases and the behavior of numerical prediction models is intended. It is, therefore, a descriptive work whose conclusions can be useful in operational weather forecast since these episodes still constitute an important challenge for numerical weather prediction models.
