Cross-checked at 5:03 AM and 5:44 PM on 9-22-2026 against tide-forecast.com's Charleston prediction page. The two sources agree to within 5 minutes and 0.15 ft on the morning high, and within 4 minutes and 0.06 ft on the evening high. This is a cross-source prediction comparison, not an observed-water-level measurement. Why does a Charleston high-tide time differ by 5–15 minutes between apps?
Before you use these numbers
These are tide predictions, not measurements. Wind, atmospheric pressure, storms, and runoff after heavy rain can make actual water levels differ. Charleston is a NOAA reference station; no subordinate-station offsets are applied. Times are local and all heights use Mean Lower Low Water (MLLW).
