Introduction: Epistaxis constitutes the main otorhinolaryngological emergency and presents a potential risk to life in cases of severe bleeding. There seems to be a seasonal correlation of the climate to epistaxis and the opinions are divided about which meteorological factor is the main responsible for nasal bleeding. Objective: To describe the prevalence, distribution, characteristics and hospital admission for epistaxis and correlate them to the climate variation. To test the hypothesis that the dry climate is associated to the increase of severity and number of hospital admission for epistaxis. Method: Retrospective study of the cases of epistaxis treated and admitted in a Tertiary Hospital of the Federal District, in the period of five years (2003 to 2007). Correlation of climate variation data obtained at the National Institute of Meteorology (INMET). Results: 194 patients with severe epistaxis were admitted. The average number of monthly internments was of 3.2. The month of July presented the highest average with 4.8, while the month of January, the lowest, with one case per month. The months with a lower and higher level of moisture were August and December, with 43.8% and 77.1%, respectively. The maximum average temperature was of 26.9ºC and the minimum was of 17ºC. There was no statistically significant correlation between moisture and temperature and the number of severe epistaxis admissions (r=0.15, p=0.20). Conclusion: The month of July presented the highest number of hospital admissions for severe epistaxis and the month of August presents the lowest moisture. The dry climate didn't present a correlation with the increase of the severity and the number of hospital admissions for epistaxis.
