Moncton tide times

Predictions: Open-Meteo Marine (MeteoFrance SMOC, 0.08° grid) — heights relative to MSL (not chart datum / LAT). Model-derived.

Model-derived from a global ocean grid. Useful indication; expect about ±45 minutes on average vs. a local harmonic gauge, individual stations vary widely. See /methodology for per-region detail. Not for navigation.

The angler tradition for major/minor fishing windows: major ≈3-hour windows around moon transit and opposition; minor ≈2-hour windows around moonrise and moonset. Times are America/Halifax local. Folk tradition, not a scientific forecast.

Moncton sits on the Petitcodiac River in Westmorland County, New Brunswick, where the Bay of Fundy's tidal energy reaches 170 kilometres inland from the open Atlantic. The Petitcodiac bore — a wave 20 to 80 centimetres high on spring tides, 10 to 20 centimetres on neaps — advances upstream through the city twice daily at approximately 12 to 15 kilometres per hour. It is visible from Bore Park on the city's south bank and from the Trans-Canada bridge, and its arrival time is posted daily. The bore is the leading edge of the tidal flood. After the bore passes, the river — which runs across a near-dry cobble bed at low water — rises steadily for the next 5 to 6 hours, reaching depths of 5 to 7 metres before the ebb begins. The full transformation from dry riverbed to navigable river takes approximately 6 hours and reverses in the same time. This is what 7 to 8 metres of tidal range does to a river 170 kilometres from the sea: it turns an urban waterway into two completely different environments within a single day. The bore is most impressive within 2 to 3 days of new or full moon, when spring tides are at their largest. The wave height varies considerably: a spring bore with a southwest wind behind it can exceed 80 centimetres and produce a distinct breaking front; a neap bore with a headwind may be barely visible. Bore arrival times are published by the CHS tide tables and are also posted at Bore Park. The wave is not dangerous to bystanders on the bank but is genuinely powerful — experienced kayakers paddle alongside the bore front on large springs, which requires whitewater skills and knowledge of the river's submerged obstructions. The Petitcodiac causeway, built in 1968, blocked tidal exchange for 42 years and reduced the bore to a trickle. The causeway gates were opened in 2010 and the full tidal exchange was restored — within a few years the bore had rebuilt to its historical intensity and Atlantic salmon began returning to the river. The bore now running through Moncton is the restored version, and the restoration is one of the more successful tidal-ecology projects in the Bay of Fundy region. Moncton is the largest city in New Brunswick and a bilingual (English-French) community. The Acadian cultural presence is strong: Acadian flag, Acadian cuisine (including poutine râpée, a dense pork-filled potato dumpling), and French-language institutions that serve the region's Francophone majority. Predictions on this page come from Open-Meteo Marine, a gridded global ocean model. Accuracy is typically within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height — model-derived, not from a local gauge.
