The fluctuating rate of suicide associated with seasonal changes is present throughout the world. An evaluation of Slovene suicide and meteorological data confirm a significant fluctuation of suicide incidence between the same months of consecutive years from 1985 to 1993. This phenomenon has been observed in all months of the year, but especially during the spring months. The research results confirm a significant correlation between suicide incidence and temperature and suicide incidence and the number of sunny hours for 1985 to 1993. The lack of significant correlation between the meteorological data and suicide incidence starting in 1994 may be interpreted as a decreasing meteorological influence on suicide incidence due to increase in antidepressant use.
