Delaware climate

Delaware has a moderate climate with average monthly temperatures that range from zero degrees (Celsius) in winter to 24 degrees in summer. More than half the days are sunny, and temperatures along the Atlantic coast are about ten degrees warmer in summer and cooler in winter.

Getting around Delaware

Delaware is 96 miles long and varies from nine miles to 35 miles in width. The best way to get around the state is by car.

Wilmington is on the main East Coast train and bus routes, but to get to other parts of the state you will need to drive.

What is good to know if travelling to Delaware?

  • Delaware is known as the “First State” as it was the first to ratify the US constitution. It is fiercely proud of this history, and there are many attractions throughout the state to reflect this. The Historical Society of Delaware is a state-wide organisation devoted to the preservation and appreciation of the state’s history. It owns three historic sites in Wilmington, all of which are worth a visit: the Old Town Hall, Willingtown Square and the Read House and Gardens.
  • Also in Wimington, the Delaware Art Museum is one of the best galleries in the state. Recently expanded in 2005, the Copeland Sculpture Park is the first of its kind in the Brandywine Valley. The park currently features nine spectacular sculptures from the museum’s own collection and one on loan.
  • For garden lovers, the Winterthur Garden in Wilmington is a must-visit. The du Pont family has shaped the history of Delaware – the huge DuPont chemical plant is one of the major industrial works in the state – but the house and garden created by Henry Francis du Pont in the early 20th century is a far more attractive monument on the landscape.
  • Delaware has some of the best beaches in the mid-Atlantic. The busiest resort is Rehoboth Beach, which boasts one of the last wooden boardwalks on the east coast – though the rest of the town is not so historic. The stretch of beach is surrounded by a golf course, hotels, shopping malls, conference centres, condos and nightclubs. Nearby Lewes is a smaller, more historic fishing town. On offer here, as well as the beach and water sports, are bird watching, fishing, hiking, biking and wine tours. The main appeal, however, are the surrounding beaches, many of which have been protected by development as state parks – ensuring long stretches of sand and not much else.
  • Though Dover is the state capital, it is much smaller in size than Wilmington and often missed by visitors. If you do visit, don’t miss Spence’s Auction and Flea Market, held every Tuesday and Friday. The market is mainly for food and vegetables – homemade sausages and preserves from the local Amish community are specialities.
  • When is the best time to fly to Delaware?

    Peak Season: Delaware’s 30 miles of Atlantic coastline are a beach haven in the summer. Many businesses, campgrounds, and services are open only for the summer season, Delaware flights are high, and reservations should be made in advance. Wilmington and the Brandywine Valley are year-round destinations. Off Season: Off-season bargains abound along the Atlantic coast. Even though many of the businesses close, if you look around you can find a place to stay. May and especially September are great times to find cheaper rates, comfortable temperatures, and quieter beaches.

  • Can I find cheaper flights to Delaware if I am willing to have stopovers?

    Yes, flights with stopovers are often cheaper than direct flights. Keep an eye out for flight deals to Delaware on Cheapflights that require 1 or 2 stops for potential cost savings.

  • Where does the fastest flight to Delaware depart from?

    For those looking to save time traveling to Delaware, Edinburgh Turnhouse offers the quickest one-way flight (7 hours 20 minutes).

  • Does Greater Wilmington have car hire?

    Yes. Those touching down at Greater Wilmington can take advantage of the car hire services offered upon their arrival.

  • Are there hotels close to Greater Wilmington?

    Yes. Greater Wilmington has hotels nearby for those requiring accommodations. Skyways Hotel New Castle, De is the closest property to Greater Wilmington (0.0 mi away from Greater Wilmington).
