Water level, last 48 hours
Measured 2.16 ft at 4:00 PM, 1.33 ft above the prediction. Highest in 48 hours: 2.74 ft at 2:42 AM.

Storm surge
Measured less predicted: +1.33 ft now; over 48 hours, −0.36 ft to +1.59 ft. Wind, air pressure and river flow move the water off the tide table.
Coastal flood thresholds
| Minor flooding | 2.6 ft |
| Moderate flooding | 3.3 ft |
| Major flooding | 5.0 ft |
The water is 0.44 ft below minor flood level now. Highest predicted tide in the next 7 days: 1.6 ft on Thu, Sep 24 at 4:04 AM, 1.0 ft below minor flooding. Thresholds are the National Weather Service’s, used for its coastal flood advisories and warnings, in feet above MLLW.

What this means
Heights are feet above mean lower low water (MLLW): the average of the lower of each day’s two low tides over NOAA’s 19-year tidal epoch, and the zero of US tide tables and nautical charts. A low tide below that average is printed as a negative height.
Predictions are astronomical. They account for the moon and the sun, not the weather: onshore wind, low air pressure and high river flow hold the water above the prediction, offshore wind and high pressure hold it below. The water level above measures the difference.
Spring tides, the largest ranges of the month, follow the new and full moon by a day or two. Neap tides, the smallest, follow the quarter moons.
