The following paper presents the analysis of meteorological variables that could in- dicate a possible effect of climate change in the City of Puebla; The study was gen- erated with data from February 2015 to December 2016, wich were downloaded from the meteorological station, located in University City, Central Campus of the Be- nemerita Universidad Autonoma of Puebla. For the analysis of these variables the Morlet mathematical method was applied within the ION-Wavelets Model; the data processed served as a hypothetical reference to correlate the effect of the “El Nino” phenomenon (possibly the bigest cause of climatic changes in the last years) in the City of Puebla. The mapping of the study with the Surfer program of each of the processed vari- ables was performed: Maximun and Minimum Temperature, Solar Radiation and Hu- midity. This was done in order to compare the meteorological changes, as well as to gen- erate the statistics of possible changes in the climate during the analyzed period.
