Plums are generally in season from May to October in the United States, with the peak season for the sweetest and juiciest plums being late summer, specifically July through September. Different varieties, such as European and Japanese plums, follow a similar seasonal timeframe. In regions like California, plum season can start as early as May and extend to October. Specialty types like Empress Plums have a shorter peak season in September. In other areas, for example Ireland, plums are mainly in season during August and September.
