Virginia Beach sits at the mouth of the Chesapeake Bay, with more water than land inside its limits and an average elevation near 12 feet. Marsh edges, tidal ditches and a long, humid summer favor mosquitoes and everything that follows them.
Virginia Beach counted 459,470 residents in the 2020 census, and 252.78 of its 497.5 square miles are water. The city sits on the Atlantic at the mouth of the Chesapeake Bay, a major portion drains to the bay through the Lynnhaven River, and its resort strip of hotels runs along the Oceanfront. NAS Oceana, a Navy fighter base, is the city's largest employer, and Naval Amphibious Base Little Creek lies mostly inside the city.
Away from the beach, the city spreads across Sandbridge, Pungo, Great Neck, Kempsville, Princess Anne, Thalia, Bayside and Ocean Park. The humid subtropical climate brings hot, humid summers from late May through late September and over 50 inches of rain in the southeastern corner near Back Bay. Mild winters and lots of standing water give insects a long season.
