Tide Times Dunmore East: Today’s High Tide, Low Tide Chart

If you’ve ever timed a kayak launch or boat departure badly, you already know that getting tide times wrong isn’t just inconvenient — it can be dangerous. Dunmore East on the Waterford coast swings between extremes: lows that leave rocks exposed and highs that push close to 4 metres. This guide cuts through the guesswork with today’s actual numbers, a practical safety rule every paddler should know, and what the data says about when you’re actually clear to launch.

Next High Tide: 06:48 · Next Low Tide: 00:19 · High Tide Height: 3.98m · Low Tide Height: 0.64m · Sunrise: 05:57

The table below consolidates key reference data for Dunmore East planning.

What time is high tide in Dunmore East today?

Today’s tide schedule at Dunmore East follows a semi-diurnal pattern — meaning two high tides and two low tides roughly every 24 hours. The next high tide is at 06:48, with the height reaching 3.98 m. These times are automatically adjusted for British Summer Time, so you don’t need to manually shift the clock when seasonal changes occur. Evening high tide typically follows around 6:33 PM, reaching approximately 4.00 m on days with standard tidal range.

Today’s high tide schedule

Based on current predictions, the morning high tide at Dunmore East occurs around 06:15 to 06:48, depending on your data source. According to TidesChart.com, on 9 August 2025 the morning high reached 3.87 m at approximately 6:17 AM. For 24 August 2025, Tides Today projects a high of 4.07 m at 7:06 AM. Minor variations between sources reflect different prediction models and rounding methods — both are considered reliable within 10-minute tolerance.

Tide height predictions

Dunmore East tide heights typically swing between 0.5 metres at low water and 4.2 metres at spring high, according to weekly charts from TidesChart.com. On 10 August 2025, a particularly high tide of 4.2 m was recorded. For paddlers and boaters, this 3.5-metre range means launch conditions change dramatically within hours — what looks safe at low tide may be inaccessible or dangerous by high water.

What time is the highest tide today?

The highest tide in a given day depends on where you are in the spring-neap cycle. During spring tides — which occur around the full and new moons — tidal range expands significantly, pushing highs closer to their maximum recorded levels. On 9 August 2025, the highest tide reached 4.09 m at 6:41 PM, according to TidesChart.com. This represents a strong spring tide, not the daily average.

Peak tide times

Peak tides occur when the moon is either full or new and aligned with the sun to produce maximum gravitational pull. On such days, the morning high on 9 August hit 3.87 m while the evening high that same day peaked at 4.09 m — a difference of 22 centimetres driven by the moon’s position in its daily cycle. For boaters planning overnight mooring, the evening peak can surprise those who launched in calmer morning conditions.

Comparison with low tides

Low tide on 9 August 2025 bottomed out at 0.75 m at 12:33 PM, according to TidesChart.com. That’s roughly one-fifth the height of the evening high. For kayakers, such a differential means the harbour shelf exposed at noon may be completely submerged by evening high — a transition requiring careful timing awareness. Low tides around 00:19 (approximately 0.64–0.95 m) expose the rocky shelf that makes Dunmore East’s coastline scenic but potentially hazardous if you’re caught unaware.

What is the 50 90 rule for tides?

The 50/90 rule is a practical safety framework used by sea kayakers and coastal paddlers to judge whether conditions are suitable for launch or paddling in tidal streams. Rather than memorising complex current tables, paddlers observe the tide’s position in its cycle and estimate flow strength based on simple reference points. The name comes from the percentages of the tidal cycle elapsed: at 50% of the cycle, current speed typically reaches its midpoint; at 90%, flow is still running strong before slackening for the turn.

Application to sea kayaking

Sea kayakers apply the 50/90 rule by watching where the water level sits relative to a known reference — a tide pole, a rock marked on a chart, or a fixed harbour feature. When the tide has risen to 50% of its range above low water, tidal streams are running at roughly half their maximum speed. At 90% of the range, currents are still significant and paddling against the flow becomes physically demanding or unsafe for less experienced groups. The safest paddling windows open near slack water — the brief period when the tide turns and flow momentarily stops.

Timing tide turns

Tide turns occur roughly every 12 hours and 25 minutes, following the lunar day rather than the solar day. This means high and low tides shift about 50 minutes later each day. For kayakers launching from Dunmore East’s harbour, slack water — the moment when tidal flow stops before reversing — may last only 10–30 minutes. According to tide prediction methodology used by NOAA and Admiralty EasyTide, slack water timing varies with local geography: headlands and narrows compress the effect, while open bays may see extended slack periods.

How long does the tide stay in before it turns?

Tides don’t pause at their peak — the waterlevel hangs near its highest point only briefly before the outflow begins. In most coastal locations, the water remains within 10–15 centimetres of high water for roughly 20–40 minutes, though this window narrows in fast-moving tidal streams like those around Waterford Bay. This “slack water at high” period is when the tidal current changes direction, creating the safest launch and retrieval window for small craft.

Tide duration at peak

The duration of peak tide depends on the slope of the tidal range curve — a concept tidal scientists call the “tidal inequality.” During neap tides, when the sun and moon’s gravitational pulls partially cancel, highs and lows flatten out and the water spends more time near peak levels. During spring tides, when both celestial bodies align, the tidal curve steepens and peaks sharpen. For Dunmore East, the 4-metre spring highs create a shorter but more dramatic high-water window compared to the gentler neap cycles that might see 3-metre highs lasting an hour or more.

Factors affecting slack water

Slack water timing and duration at Dunmore East are shaped by local geography: the shape of Waterford Harbour, the approach channels, and the nearby Hook Head constriction all influence how quickly the tide turns. Local sailing clubs and kayak operators who launch regularly from the area develop an intuitive sense of these patterns, but newcomers should treat initial trips with caution and ideally go with someone familiar with local conditions. According to VisitMyHarbour, monthly tide tables for Dunmore East are available and include slack water estimates for harbour users.

Are tides stronger during a full moon?

Yes — tides are measurably stronger during full moons and new moons, a phenomenon called spring tides. The term has nothing to do with the season; it comes from the German word “springen,” meaning “to leap.” During these lunar phases, the sun and moon align their gravitational pulls, amplifying the tidal range by up to 30–40% compared to neap tides when they form a right angle. At Dunmore East, this means highs during spring periods can push toward 4.2 metres while lows may drop below 0.5 metres, creating dramatic exposed reef conditions.

Spring tide effects

Spring tides occur roughly twice per lunar month, approximately every 14 days. The effects are most pronounced around the equinoxes (March and September), when the moon’s orbital path aligns most directly with Earth’s equator, intensifying the gravitational differential. During these periods, Dunmore East paddlers and boaters can expect stronger-than-average currents, more rapid water-level changes, and shorter windows at high and low water. Launch and retrieval points that are safe during neap tides may become dangerous or completely impassable during spring periods.

Moon phase influence

Beyond the full and new moon timing, the moon’s distance from Earth in its elliptical orbit also affects tide strength. When the moon is at perigee — its closest point to Earth — gravitational pull increases slightly, producing “perigean spring tides” that can push extreme highs higher than normal. Tides4Fishing records show solunar coefficients for the Dunmore area ranging from 94 to 96 during May 2025, indicating very high fish and marine activity periods correlated with strong tidal movements. These periods offer excellent conditions for experienced paddlers seeking tidal flow challenges but are unsuitable for novices or those unfamiliar with the area’s specific hazards.

For paddlers and boaters at Dunmore East, the choice is straightforward: check live tide tables before every launch, apply the 50/90 rule to gauge current speed, and treat spring tide periods with extra caution. The data shows that most drowning incidents involve people who skipped the life jacket — not people who were caught in unexpected conditions. Wear your PFD, time your launch around slack water, and let the numbers rather than guesswork dictate when you go out.
