A statistical analysis is carried out for the characterization of water quality in seven sampling points of beaches of the Colombian Caribbean tourist sector, the monitoring was developed during the months of February, March, April and September 2016, the parameters analyzed in detail were nitrites, nitrates, phosphates, fecal coliforms and total coliforms. descriptive statistics, correlation analysis were determined, an ACP was carried out to complement the relationship between the variables and the characteristics of the beaches with respect to them, a cluster analysis and the Kruskal Wallis test. The results show high dispersion in the variables; as well as important associations between the variables nitrites and nitrates, as well as for fecal coliforms and total coloforms. The descriptive statistics show high variations of the variables in the different beaches and different months, having coefficients of variation higher than 30%. The Kruskal-Wallis test indicates that there is a significant difference of 10% between the medians of the months considered, with respect to the nitrite and faecal coliforms variables; being in the months of March and April where the highest values and the highest dispersions in the contents are presented.
