The Parrish Art Museum travels to another seaside idyll with “Abstract Climates: Helen Frankenthaler in Provincetown” through October 27. Created during the late artist’s summer escapes to the Cape beginning in the mid-20th century, paintings and works on paper explore her studies of abstraction and landscapes. Her stepdaughter Lise Motherwell co-curated the breathtaking exhibit. 279 Montauk Highway, Water Mill; 631.283.2118; parrishart.org
