One-day water-level lead direction differed across three adjacent US Atlantic gauge pairs in retained 1960-2024 records
We tested one-day timing in daily water-level midpoint anomalies at four US Atlantic tide gauges. We used 28 fixed NOAA source objects for 1960-2024. We removed each station-year-month mean and compared north-to-south and south-to-north lead correlations on the same dates. The correlation differences were -0.191 for Boston and The Battery, +0.217 for The Battery and Sewells Point, and +0.087 for Sewells Point and Charleston. The 98.33% five-year block intervals excluded zero for all three pairs. Each sign repeated in 1960-1992 and 1993-2024. Thus the data did not show one common lead direction. A planned season check gave opposite winter and summer signs for Sewells Point and Charleston. The midpoint is not a daily mean or a tide-removed measure. Tides, weather, daily time limits, local response, and missing data can affect the estimates. The result does not identify a wave, causal path, speed, or forecast skill. The package gives source hashes, fixed daily evidence, code, uncertainty draws, figures, and a separate numerical audit.
