The best finds turn up after storms, on big spring tides, at low water. We score the next 7 days and tell you what to look for along the strandline each day.
Storms churn the seabed and wash new treasure up the beach.

A day near low water on a spring tide (new or full moon, large range) is the classic 5-star beachcombing day, especially after a storm. A normal low-tide day rates about 3; a high-water, small-range day rates 1. We read spring/neap from the lunar age (new-moon anchor 2000-01-06) and add a storm bonus that decays over a few days.
