Delaware RV seasonal calendar

Weather: Typical 43°F high / 26°F low

Activities: Winter waterfowl on Bombay Hook's wildlife drive · Off-season boardwalk walks in Rehoboth · Storm-watching at Cape Henlopen

RV trip: Quiet winter on the coast — empty boardwalks, cold sea light, and big flocks of wintering waterfowl on the refuges. A contemplative month, not a camping one for most.

Considerations: Many coastal campgrounds close or run limited winter services — confirm before you come.

Best rigs: Motorhomes & RVs · Trucks & van conversions

Weather: Typical 47°F high / 28°F low

Activities: Snow geese in the refuge impoundments · Empty-beach walks at Delaware Seashore · Cozy restaurant days in Lewes

RV trip: Late winter stays raw near the water, but clear days are bright and utterly uncrowded. Best for short trips built around birds and beach walks.

Considerations: Wind chill off the Atlantic bites harder than the thermometer suggests; nor'easters are possible.

Best rigs: Motorhomes & RVs · Trucks & van conversions

Weather: Typical 54°F high / 35°F low

Activities: Early-spring birding at Prime Hook · First mild-day rides on the coastal trails · Cape Henlopen's quiet dunes

RV trip: The turn toward spring — ospreys return, refuges stir, and mild afternoons multiply. Beaches remain blissfully empty.

Considerations: The ocean stays winter-cold and some facilities remain shuttered into April.

Delaware in March — the full guide

Weather: Typical 64°F high / 44°F low

Activities: Spring shorebirds arriving on Delaware Bay · Camping at Cape Henlopen before the rush · Bald-cypress green-out at Trap Pond

RV trip: Spring proper, and the start of Delaware's best stretch — mild, green, and calm before beach season. Ideal for coast-plus-countryside loops in a state you can cross in an hour.

Considerations: Spring weekends begin filling the state-park campgrounds; nights still get chilly.

Delaware in April — the full guide

Weather: Typical 74°F high / 54°F low

Activities: Horseshoe crab spawn on moonlit high tides · Shorebird peak at Bombay Hook · Warm-day camping at the Seashore parks

RV trip: May is the bay's famous month: on new- and full-moon evening high tides, horseshoe crabs crawl ashore to spawn and red knots arrive to feast. Shorebird peak meets fine camping weather.

Considerations: Peak spawn nights follow the moon, not the weekend — check the tide calendar. Beach-town traffic starts building.

Delaware in May — the full guide

Weather: Typical 82°F high / 63°F low

Activities: Firefly Music Festival in Dover (mid-June) · First swim-warm ocean days · Evening rides on the Junction & Breakwater Trail

RV trip: Early summer is Delaware at its best — warm sand, warm evenings, and the Firefly festival bringing a big June weekend to Dover. The full beach season is running by month's end.

Considerations: Festival and beach weekends fill campgrounds fast; Route 1 crawls on summer Saturdays — arrive off-peak.

Delaware in June — the full guide

Weather: Typical 86°F high / 68°F low

Activities: Boardwalk evenings in Rehoboth · Surf fishing at Delaware Seashore · Slow mornings on the bay beaches

RV trip: Peak beach season — hot, bright, busy, and fun. Camp near the sand and let the days organize themselves.

Considerations: This is the most crowded month on the coast; reservations and patience with traffic are both required.

Best rigs: Motorhomes & RVs · Trucks & van conversions

Weather: Typical 85°F high / 67°F low

Activities: Warmest surf of the year · Kayaking the inland bays · Sunset crabbing docks

RV trip: High summer holds — the ocean is at its warmest and the towns at their liveliest. Late August softens as families head home.

Considerations: Tropical-system remnants can brush the coast from late August; keep an eye on marine forecasts.

Best rigs: Motorhomes & RVs · Trucks & van conversions

Weather: Typical 78°F high / 60°F low

Activities: Warm-ocean swims without the crowds · Fall shorebirds moving through the refuges · Quiet boardwalk evenings

RV trip: Locals' favorite month — the water holds summer warmth while the crowds vanish. September beach camping is the state's quiet prize.

Considerations: Peak hurricane season for the Atlantic — most days are gorgeous, but watch the tropics.

Delaware in September — the full guide

Weather: Typical 68°F high / 48°F low

Activities: Geese arriving at Bombay Hook · Sea Witch weekend in Rehoboth (late October) · Fall color at Trap Pond's cypress swamp

RV trip: Crisp, golden, and still mild by northern standards. Big flights of Canada and snow geese arrive on the refuges through the month.

Considerations: Nights turn cold enough for real bedding; some seasonal facilities begin winding down.

Delaware in October — the full guide

Weather: Typical 57°F high / 39°F low

Activities: Fall waterfowl peak on the wildlife drive · Last mild-day hikes at Cape Henlopen · Early holiday lights in Lewes

RV trip: Late fall is the refuge system's crescendo — the fall waterfowl peak lands this month against bare-tree quiet everywhere else.

Considerations: Campground options thin considerably in November; confirm what's open and winterize for freezing nights.

Delaware in November — the full guide

Weather: Typical 47°F high / 31°F low

Activities: Holiday strolls in Lewes and New Castle · Winter birds on Delaware Bay · Clear-day lighthouse views at the Cape

RV trip: Winter quiet returns to the coast. Short days, sea-smoke mornings, and holiday-dressed small towns make for gentle day trips more than camping.

Considerations: Most camping is closed for the season; the few open options run winter rules.
