When you’re contemplating the waves as they crash on to the shore it can be difficult to remember that Long Island is a part of New York city. This exciting island is a favourite with surfers and beach lovers, and lies in the Atlantic ocean to the east of New York Harbour.
Thanks to good transport links, you can reach Long Island from any other part of the US, and international flights make getting to the beach from further afield relatively simple. The beaches of Long Island sound are fabulous, and fans of ‘The Great Gatsby’ will adore the North Shore.
The water temperature at Long Island sound ranges from winter lows of around 35F or 1.6C in February when it is at its coldest to around 72F or 22.2C in August when it is warm enough for surfing in a surf vest and board shorts and pleasant for swimming.
The water temperature climbs steadily from the spring onwards, and South Shore in particular is a haven for surfers. You will need a wetsuit during spring and autumn, but excellent waves have made Long Island one of the most famous surfing locations in the world, and the sport is popular with locals and visitors.
