About Saint John, NB Tide Times
Saint John, NB is located on the North American coastline in Canada. The tide predictions shown above cover 7 days of high and low tide times, updated daily using professional-grade harmonic tidal analysis. Tide heights are displayed in metres above Chart Datum (CD), the standard reference level used in marine navigation charts.
Tidal patterns at Saint John, NB are driven by the gravitational forces of the Moon and Sun acting on the local ocean. The timing and height of each tide depends on the shape of the local coastline, water depth, and the position of celestial bodies relative to Earth. Like all coastal locations, Saint John, NB experiences a full tidal cycle approximately every 24 hours and 50 minutes.
Spring tides — which occur at new moon and full moon — produce the largest tidal ranges at Saint John, NB, with higher high tides and lower low tides than average. Neap tides, at the quarter moons, produce the smallest ranges. This fortnightly cycle is an important consideration for anyone planning coastal activities in the area.
Who Uses Tide Predictions for Saint John, NB?
🎣 Fishermen & Anglers
Fish are most active around tide changes, particularly the two hours either side of high and low water. Anglers targeting shore fish near Saint John, NB use tide predictions to plan sessions when water movement is at its most productive.
⛵ Sailors & Boaters
Navigating in and out of harbours and estuaries near Saint John, NB safely requires knowing the state of the tide. Sailors rely on these predictions to avoid running aground in shallow water and to time passage through tidal channels.
🏄 Surfers & Water Sports
Many surf breaks and water sports venues near Saint John, NB are tide-dependent. Certain breaks work only on a specific tide height, while kayaking and paddleboarding routes can be heavily affected by tidal currents and water depth.
🏖️ Beachgoers & Walkers
Tidal beaches, coastal paths, and rock pools near Saint John, NB are accessible only at certain tide states. Checking tide times before visiting ensures you don't get cut off by a rising tide, and helps you find the best time to explore exposed sand and rocky shores.
How to Read the Saint John, NB Tide Chart
The tide chart above plots predicted water height (in metres) against time for Saint John, NB. The curved line rises to peaks (high tide) and falls to troughs (low tide). The height shown is measured above Chart Datum — a reference level set near the lowest predicted astronomical tide level for the area.
- HWHigh Water — the peak of the tide. This is when the sea is at its highest level. The exact time and height changes each day.
- LWLow Water — the trough of the tide. The sea is at its lowest level, often exposing rocks, sand, and mudflats.
- ↑Flood tide — the period when the tide is rising from low water to high water. Currents flow onshore or up estuaries during this phase.
- ↓Ebb tide — the period when the tide is falling from high water to low water. Currents flow offshore or down estuaries during this phase.
All times shown are in the local timezone for Saint John, NB (America/Moncton). Remember that tide times advance by roughly 50 minutes each day, so always check the chart for your specific visit date.
Frequently Asked Questions — Saint John, NB Tides
How many tides does Saint John, NB have per day?
Most coastal locations, including Saint John, NB, experience two high tides and two low tides every 24 hours and 50 minutes — this is called a semidiurnal tidal pattern. Some regions experience one tide per day (diurnal), or a mixed pattern. The exact cycle for Saint John, NB is shown in the chart above.
How accurate are tide predictions for Saint John, NB?
Astronomical tide predictions for Saint John, NB are typically accurate to within 15–30 minutes and a few centimetres. However, actual water levels can vary due to weather — strong onshore winds raise sea levels, while offshore winds lower them. Storm surges and low atmospheric pressure can add significant height. Always treat predictions as a guide and check local conditions before heading to the coast.
What is Chart Datum and why is it used?
Chart Datum (CD) is the reference level from which all tide heights at Saint John, NB are measured. It is set close to the Lowest Astronomical Tide (LAT) — meaning tide heights are almost always positive numbers. Chart Datum is also the reference used on nautical charts for water depth, so mariners can add the predicted tide height to the charted depth to calculate the actual depth of water at any given time.
Why do tide times change every day?
Tides are caused by the Moon's orbit around the Earth, which takes approximately 24 hours and 50 minutes to complete one tidal cycle. This means high and low tides at Saint John, NB occur about 50 minutes later each day. Over a month, this adds up to a complete shift through the clock. The height of tides also changes through the monthly cycle between spring and neap tides.
