About the tides at Dahlgren, Upper Machodoc Creek, Va.
Dahlgren, Upper Machodoc Creek, Va. gets two high tides and two low tides almost every day, and the two highs are close in height. Over the next month the water typically rises or falls about 1.5 ft between a high and the next low.
The biggest swings in this window come around Tuesday, October 27, when the day's range reaches 2.2 ft, and again around Sunday, October 11 (2.0 ft). Those spring tides follow the new and full moon by a day or two. The calmest day is Monday, October 19, with only 1.1 ft between the day's highest and lowest water.
The lowest tide of the month is 0.1 ft at 10:10 AM on Tuesday, October 27.
The highest predicted tide is 2.3 ft at 4:16 PM on Tuesday, October 27. Onshore wind or a storm can push the real water level above that.
This is a reference (harmonic) station: NOAA predicts its tides directly from years of measured water levels here, which makes it among the most reliable predictions on the coast.
