Cavendish, PEI tide times

Mean tidal range at Cavendish is approximately 0.7 metres; spring range is around 0.9 metres. This is noticeably lower than PEI's south coast (Charlottetown, 1.2 m) or Summerside (1.8 m), reflecting the north shore's Gulf of St. Lawrence exposure and its weaker tidal forcing. The practical effect is that the beach width changes modestly through the tidal cycle — the full beach is largely accessible at all states of tide. At low water the intertidal zone extends further offshore and the water is shallower for a longer stretch from shore, which affects swimming depth access. The modest range also means rip current risk is relatively low compared to macrotidal beaches.

Lucy Maud Montgomery was born in Clifton (now New London), PEI in 1874 and grew up largely in Cavendish after her mother's early death, living with her maternal grandparents. She set her 1908 novel Anne of Green Gables in the Cavendish countryside, using the neighbouring Macneill farm — known as Green Gables — as the physical model for the home of Anne Shirley. The house, now Green Gables Heritage Place and part of PEI National Park, is preserved as a national historic site. Montgomery is buried in the Cavendish cemetery. The novel has been continuously in print since 1908 and has been translated into 36 languages; the Anne of Green Gables franchise is a significant driver of PEI's tourism economy.

Late July and the first two weeks of August are the peak window for swimming at Cavendish — Gulf of St. Lawrence water temperatures reach 20°C or slightly above, the beach is at full summer development, and the national park lifeguard service is operating. The water is warmest in the afternoon after a day of solar heating of the shallow Gulf. Earlier in July the water is 16 to 18°C, which is swimmable but noticeably cooler; by late August temperatures begin dropping back toward 17 to 18°C. The beach faces northwest, so afternoon sun warms the sand until early evening.

North Rustico Harbour, 5 kilometres east of Cavendish, is a small working fishing harbour where the lobster fleet lands its catch — the contrast with the commercial Cavendish strip is sharp. Brackley Beach (10 km east) and Stanhope Beach (15 km east) are national park beaches with fewer facilities and better dune system integrity than Cavendish. The Cavendish Boardwalk trail within the national park walks the dune-beach boundary. New London Bay and Rustico Bay, both accessible from Route 6, are warm shallow bays where kayaking on a falling tide reveals sandbars and estuary birds. PEI's Confederation Trail, a converted railway right-of-way, passes through Cavendish and is accessible for cycling year-round.

No. The predictions shown here come from Open-Meteo Marine, a global ocean model with typical accuracy of plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height. They are appropriate for general beach and coastal planning — understanding the tidal cycle, timing a kayak on the estuary, or reading beach conditions — not for vessel navigation or any safety-critical decision.

Cavendish sits within an exposed section of the Gulf of St. Lawrence; wind-driven storm surge in autumn and winter can significantly exceed predicted tide heights.
