South Carolina

Folly Beach

Charleston's surf town. Erosion at the Washout area exposes shell hash full of teeth - best on a low spring tide.

Solid hunting day. Best window opens around the 8:45 PM low (0.9 ft). Brisk S winds (17 mph) — expect chop; seas 4 ft+ — murky and choppy.

Next 3 days: Today is the pick (69); Thu runs cooler at 59.

▼ means the forecast wind will likely push the real low below NOAA's prediction (more beach to hunt). ▲ means it will likely sit above the prediction (less beach). Rough rule: ~0.04 ft per mph of sustained wind during the low-tide window.

🌤️ Weather & Wave Forecast

Impact on visibility and stir-up over the next 5 days.

Onshore Wind: Pushes water in (tide sits higher) and stirs up the bottom. Good for "new" teeth, bad for visibility.

Offshore Wind: Water blown out (tide sits lower). Maximum beach exposure for hunting the low tide line.

Analysis

Solid. Reliable productivity expected.

Tide range

41.3 / 50

Today's swing is 5.0 ft (saturates at 6 ft = 50 pts).

Spring tide

1.8 / 15

Within ±2 days of a new or full moon = wider swing.

Daylight timing

6.8 / 15

Low in daylight = you can actually hunt.

Recent stir

0.0 / 10

Past 72h onshore wind churn (only counts hours that already happened).

Wind setup at low

-0.4 / 10

Forecast wind piles 0.1 ft of water around the low.

Surf bonus

5.0 / 5

1–4 ft of recent surf = clean sorting; >7 ft = unfishable.

Recent rainfall

0.0 / 3

No measurable rain in the past 48h — no runoff signal.

Storm multipliermultiplier

1.15×

Peak gust 30 mph triggers post-storm boost.

Event boostadded

Manual + auto events (storms, drought, beach renourishment).

Why not higher? The biggest unused headroom today is spring tide (+13.2 pts available). A day with that maxed out would score around 82.

Show the math

components: 41.3 + 1.8 + 6.8 + 0.0 + -0.4 + 5.0 + 0.0 = 54.5 × storm multiplier 1.15 = 62.7 + event boost +6 = 68.7 final = 69

What's NOT in this score

We are deliberate about which factors to include. These are not currently in the model:

Hunt pressure. A “hunts this week” chip is shown on each location page for transparency, but it does not change the score yet. We need more outcomes per site before a penalty would be statistically meaningful.
Wave period / swell direction. We use wave height only. Long-period groundswell sorts material differently than short wind chop, but Open-Meteo doesn't expose period reliably.
Barometric pressure trend. Falling pressure = approaching storm = building stir. Currently we wait for the wind to actually arrive.
Water temperature, clarity, salinity. Affects comfort but not (directly) what teeth wash up.
Weekday vs weekend. A 70 on Tuesday is often better in practice than a 70 on Saturday because of crowds, but we don't adjust for that.
Beach renourishment. Fresh sand buries everything. We capture this only when an admin logs a manual event — there's no auto-detection.

If you think we should add one of these, log a hunt with notes — every rated outcome helps us decide which signals actually predict tooth count.
