Measurable snow is rare in San Clemente: the 1991–2020 normal rounds to zero — only a trace in most years, and nights reach freezing on about 15 days a year. When snow or ice does arrive, it causes outsized trouble because roads are rarely treated — watch for Winter Weather Advisories and Freeze Warnings.
