About this data: method, sources and free downloads
Since 1996, NOAA's Sewells Point tide gauge has recorded water high enough for FloodRoute's model to put at least one Lynnhaven road at risk on 106 days, about 3 a year. The highest water was 7.89 ft on Thursday, September 18, 2003, 5.18 ft above the tide tables; at that level the model estimates 14 Lynnhaven roads were at risk, including Hutton Lane, Arrowfield Road and South Kings Road. Those days have become more common: about 2 a year in 1996–2005, versus 5 a year in 2016–2025.
For every day since 1996 we take NOAA's verified highest observed water at the tide gauge, adjust it to the town's prediction station exactly as the live forecast does (the gauge's departure from the tide tables, minus the departure already built into our calibration), and run FloodRoute's flood model on today's road network and street elevations. A day counts when at least one road in the town is at or below that water level by the model's rules. Rain is not included, so wet days were likely worse.
Gauge: NOAA 8638610 (Sewells Point). Heights are feet above MLLW.

FAQ
Lynnhaven flood history: questions, answered
How often do roads flood at high tide in Lynnhaven?
By FloodRoute's estimate, at least one Lynnhaven road was at risk on 106 days between 1996 and Sep 30, 2026, about 3 a year. Those days have become more common: about 2 a year in 1996–2005, versus 5 a year in 2016–2025. Most of those days are shallow water on a few low streets; the biggest days put dozens of roads at risk.
What was the highest tide in Lynnhaven since 1996?
Thursday, September 18, 2003: NOAA's Sewells Point tide gauge recorded 7.89 ft (MLLW), 5.18 ft above the tide tables. At that level FloodRoute's model estimates 14 Lynnhaven roads were at risk, including Hutton Lane, Arrowfield Road and South Kings Road.
When did a high tide last put Lynnhaven roads at risk?
The most recent day in the verified record is Sunday, September 27, 2026: 5.15 ft at the Sewells Point gauge, 1 road at risk. NOAA verifies data with a lag of a month or two; the live forecast covers today and the weeks ahead.
Is this a record of actual flooding in Lynnhaven?
No. Estimates, not records of actual flooding. Each day is NOAA's verified high water at the tide gauge, run through FloodRoute's flood model on today's roads and elevations, in dry weather. Drains, levees, tide gates, rain, road changes and elevation error all mean real conditions differed. Not for property, real-estate, insurance, lending, engineering or legal decisions. Neighbor flood reports in the FloodRoute app are the ground truth we use to check and improve the model.
