Delaware Weather & Climate Guide 2026

Delaware's climate in numbers — the months that flatter it, the ones to avoid, and what to pack.

Delaware, the First State, packs remarkable diversity into the nation's second-smallest state — from the cosmopolitan Wilmington riverfront and historic New Castle's cobblestone streets to the Victorian beach resort of Rehoboth Beach and the wild marshes of Cape Henlopen. Rich in colonial and Revolutionary War history, home to major corporate headquarters and the DuPont dynasty's legacy estates, and bordered by Atlantic beaches, Delaware rewards visitors who look beyond its modest size.
