This study carries forward the study of seasonal variation of suicide within the United States. Suicides occurring within Florida (n=52,582) between 1970 and 2002 were analyzed using chi-square analysis. The examination of the seasonality of suicide by age group, sex, method, and secular trends was completed as well. Within Florida suicides exhibited a significant peak occurrence during the spring and summer, while the winter is the significant trough season. Drowning suicides peaked during the summer, and other/unreported suicide methods peaked during the winter. Suicides for individuals 65 and older peaked during the spring, which is a finding unique to this study. There were no significant findings in the analysis of seasonality of suicide by sex. There was no evidence of a decreasing trend in the occurrence of seasonality of suicide over the three decades studied. Implications for research and practice are discussed.
