Everything you need to know about your flight to Delaware
Delaware has a moderate climate with average monthly temperatures that range from 32 degrees (F) in winter to 76 degrees in summer. Over half the days are sunny, and temperatures along the Atlantic coast are about 10 degrees warmer in summer and cooler in winter.
Peak Season:
Delaware’s 30 miles of Atlantic coast are a beach haven in the summer. Many businesses, campgrounds, and services are open only for the summer season, prices 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.
Delaware is 96 miles long and varies from 9 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.
