Two hundred and twenty-eight patients of epistaxis were treated in Hakodate Municipal Hospital from July in 1980 to June in 1981. The patients' ages ranged from 0 to 70 years. There were 130 males and 98 females.The origin of epistaxis was classified into local (37.1%), systemic (28.7%) and essential causes (34.2%). For these patients, the relation between the incidence of epistaxis and weather conditions was investigated. As a result, a high incidence of epistaxis was observed to be closely connected with the following three atmospheric factors: i) dryness of the air, ii) approach of low atmospheric pressure and iii) passage of a cold front.In the Hakodate district, high incidences of epistaxis were observed in January and in the period from March to April when there were frequent passages of cold fronts accompanied by low atmospheric pressure.
