Which way is the water going?

180° is dead head-on, 0° is running the same way. Anything past 135° is opposing within 45 degrees — the case that stacks water up. At 4 s this sea would stop dead against about 3.1 kt of opposing current.

The flood is moving at 0.67 kt toward NNW, into a 3.5 ft at 4 s sea. About 10% taller and 9% shorter than the open-water figure, so roughly 1.2× the steepness. At 4 s the sea stops dead against about 3.1 kt of opposing current, and this is 18% of the way there. Not dramatic yet, but the sea is already shorter than the number says.

ACT6336 "Fort Macon, 0.6 mile SE of", 0.3 nm away. It is the closest current NOAA publishes to this inlet. Bin 1 — the only bin NOAA publishes here, listed at 6 ft. NOAA publishes only slack and maximum events for this subordinate station — no hourly series exists — so the hours between them are shaped from its own events and marked as such.

Next turn: slack at 13:53

Also within 3 nm, and deliberately not averaged in: ACT6341 (0.6 nm), ACT6396 (0.9 nm), ACT6391 (0.9 nm), ACT6346 (1.1 nm), ACT6331 (1.2 nm), ACT6381 (1.3 nm), ACT6326 (1.7 nm), ACT6351 (1.8 nm), ACT6366 (2.2 nm), ACT6371 (2.5 nm), ACT6356 (2.5 nm), ACT6401 (2.6 nm), ACT6376 (2.8 nm), ACT6406 (2.9 nm).

180° is dead head-on, 0° is running the same way. Anything past 135° is opposing within 45 degrees — the case that stacks water up. At 5 s this sea would stop dead against about 3.8 kt of opposing current.

The flood is moving at 0.64 kt toward NE, into a 4.2 ft at 5 s sea. About 9% taller and 9% shorter than the open-water figure, so roughly 1.2× the steepness. At 5 s the sea stops dead against about 3.4 kt of opposing current, and this is 17% of the way there. Not dramatic yet, but the sea is already shorter than the number says.

CFR1615 "Myrtle Sound, south end, ICW", 0.8 nm away. NOAA's own name for it says ICW, so this meter is in the waterway behind Carolina Beach Inlet, not on the bar. Bin 1 — the only bin NOAA publishes here, listed at 16 ft. Hourly values come straight from NOAA's harmonic series for this station.

Next turn: slack at 12:46

Also within 3 nm, and deliberately not averaged in: CFR1616 (1.3 nm), CFR1614 (2.8 nm).

180° is dead head-on, 0° is running the same way. Anything past 135° is opposing within 45 degrees — the case that stacks water up. At 4 s this sea would stop dead against about 3.4 kt of opposing current.

The ebb is running at 1.4 kt toward SSE, straight into a 2.6 ft at 4 s sea. About 22% taller and 17% shorter than the open-water figure, so roughly 1.5× the steepness. At 4 s the sea stops dead against about 3.1 kt of opposing current, and this is 33% of the way there. Steeper and closer together than the height alone suggests.

CFR1625 "Fort Caswell", 1.3 nm away. It is the closest current NOAA publishes to this inlet. Bin 1 of 3, the one NOAA lists at the smallest distance (12 ft) — the fastest-running bin at this station, which is the water a hull is in. Hourly values come straight from NOAA's harmonic series for this station.

Next turn: slack at 14:35

Also within 3 nm, and deliberately not averaged in: CFR1626 (1.9 nm), CFR1624 (2.9 nm).
