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 UTC local. Folk tradition, not a scientific forecast.

Next spring tide on Mon 18 May (range 5.0m). Last neap on Wed 13 May.

Spring tides cluster around new and full moons (biggest swings). Neap tides land on quarter moons (smallest swings). See the spring tide and neap tide glossary entries for the why.

Tadoussac stands at the confluence of the Saguenay Fjord and the St. Lawrence estuary, and the tidal regime here is among the most dramatic on the Canadian Atlantic seaboard. Spring range reaches 5.8 m above chart datum. At high water the Saguenay mouth is a wide black bay; four hours later the full ebb has carved it down to exposed ledge and current-scoured gravel. The hydraulic at the fjord entrance — locally called le batailleur, the brawler — generates standing waves and boils on a spring ebb that make it unmistakeable from the ferry crossing. This current is not swimmable and should not be paddled without advanced open-water skills and local knowledge of the timing windows. The tidal exchange is also the reason Tadoussac is the best whale-watching location in eastern North America. Cold, nutrient-rich water from the Saguenay meets the warmer surface layer of the St. Lawrence on every tidal cycle, driving upwellings that concentrate krill and small fish year-round. Beluga whales are present in the estuary in every month; a resident population of around 60 individuals feeds on the mixing zone and can often be seen from the cape west of the ferry dock. Blue whales, finback whales, minke whales, and humpback whales arrive in May and June when the capelin spawn on the shallow offshore banks and remain through October. July and August are the peak weeks for multi-species sightings. Whale-watching boats operating from the Tadoussac quay run morning and afternoon sailings. The morning flood tide is the most productive for belugas close to shore; afternoon trips on the ebb push further out to the blue and finback grounds. For sea kayakers, Tadoussac requires careful planning. The current in the Saguenay mouth at mid-tide reaches 4 knots on springs and makes crossing the fjord entrance inadvisable. The sheltered cove immediately east of the hotel — Anse à l'Eau — is accessible from two hours before to two hours after high water and is one of the best beluga-viewing spots on the water. Paddle silently, stay 100 m from any animal, and let the current work for you on the return leg. Families come to Tadoussac for the dune-backed sand beach between the hotel and the quay. The beach is small, perhaps 250 m, but protected from the prevailing northwest wind and sandy to the waterline at all tidal stages. Water temperature peaks at around 14°C in August — cold by southern standards but workable. The beach itself is safe for children except at peak ebb when a rip runs along the western end; stay east of the breakwater rocks. The historic site at Tadoussac includes the oldest surviving wooden chapel in North America (1747) and the location of the fur-trading post established in 1600 — considered the oldest permanent European trading post on the continent. The post site is on the elevated ground above the beach and gives an elevated view of the fjord mouth and the current. Birdwatchers find the cape and the point east of the ferry dock productive year-round. Common eiders, black guillemots, and razorbills are resident; migrant shorebirds work the tidal banks in August and September. Peregrines hunt the duck flocks on the ebb. In winter, harlequin ducks feed in the tidal rush below le batailleur. Anglers target Atlantic cod in the deep channel below the fjord mouth on the early flood, jigging from the quay or from small charter boats. Brook trout descend the Saguenay tributaries in September on the first autumn rains; tidal-influenced pools at river mouths hold fish on the incoming water.
