Martha’s Vineyard is an island located south of Cape Cod in Massachusetts, known for being an affluent summer colony. It includes the smaller Chappaquiddick Island, which is usually connected to the larger island, though storms and hurricanes have been known to separate the two islands. The last such separation of the islands was in 2007, and as of April 2, 2015, the two islands are again connected.Often called just “The Vineyard”, the island has a land area of 100 square miles (260 km2). It is the 58th largest island in the United States and the third largest on the East Coast of the United States. It is not connected to the mainland by a bridge or tunnel.

Owing to the influence of the Atlantic Ocean, temperatures below 0 °F (-17.8 °C) are rare, occurring at least 1 day per year and most days during the winter months rise above freezing. The average annual snowfall is 25.3 inches (643 mm). Summers are warm and mild with temperatures rarely exceeding 90 °F (32.2 °C), with only 1 or 2 days reaching or exceeding it. During the summer months, the island’s warmest months (July and August) average around 71.5 °F (21.9 °C).
