It’s officially horseshoe crab season in Delaware! The Delaware Bay is the largest spawning area in the world for horseshoe crabs, and every spring from May to late June, tens of thousands of horseshoe crabs will lay their eggs on the shores of the Delaware Bay. You don’t want to miss it. 

Here are the best days to see horseshoe crabs in 2019:

May 2-7: New Moon

May 16-21: Full Moon

June 1-5: New Moon

June 15-19: Full Moon

These dates are based on when new moons and full moons happen in the months of May and June, 2019. Check a tide chart, and time your horseshoe crab hunting at night during high tide. Now that you know when to see the horseshoe crabs, I also wrote an entire blog about how to see them, and you can check that out here. 

Happy horseshoe crab season!
