The Highest Tides Ahead

The biggest predicted high tides over the next six weeks — the dates worth noting in advance. For whether wind and surge are piling water on top of one this week, see High Water Watch.

Where the water goes

Main Street and the Edgewater Street waterfront

The low ground along the harbour is the first to flood when a high tide meets a storm surge. Post-tropical storm Lee (16 September 2023) pushed water about 1.5 m over the normal high tide and flooded properties along Main Street. Residents say a southeast wind is the worst case, because it drives the water straight into the head of the bay.

In front of the three churches (Edgewater Street)

The Town built a living shoreline here in 2022 to soften storm-surge flooding on the stretch of Edgewater Street most exposed to a high tide riding on a surge. It is an adaptation, not a wall — the water can still come up on the biggest tides and storms.

How to read this

These are official astronomical tide predictions, in m above chart datum. They tell you how high the water would rise on the tide alone, on a calm day.

Whether water actually reaches the street depends on wind, rain and storm surge on top of the tide. This is not a flood forecast. For warnings, follow the channel below.

About the predictions

These predictions are for the Canadian Hydrographic Service's Mahone Harbour station, right in the town at the head of the bay, so they read the water at Mahone Bay itself. Heights are in metres above chart datum — the low-water level the nautical charts are drawn from — not the depth of water on any street.
