The state's signature
Horseshoe crab spawn on Delaware Bay
On May's new- and full-moon evening high tides, an armored spawn 400 million years in rehearsal crawls ashore — and red knots time a hemisphere-length flight to eat the eggs. Peak nights are moon math, published by the survey.
Seasonal RV-timing verdict
When Delaware is at its best
Delaware's prime RV window is April to June and September to October. Mild spring and fall avoid both summer beach crowds and winter chill; coastal areas are pleasant for RVing. Shoulder-season play: March and November offer good beach camping rates but water temperatures remain cold and some facilities close early.
Know before you go
Hurricanes and nor'easters can affect the coast in late summer and fall. Summer traffic on Route 1 is heavy on weekends.
