Tide times Rosslare

Rosslare Harbour is Ireland's ferry port for Wales and France. The gauge serves Rosslare Strand, a long shelving Blue Flag beach, and the south Wexford coast towards Carnsore Point.

Today, Fri, 16 Oct: high water at 09:15 (0.8 m) and 21:25 (0.7 m), low water at 03:00 and 15:20. The tide table below gives high and low water for the next 7 days, in Irish local time, and the calendar runs 30 days ahead. These predictions also serve Rosslare Strand, Rosslare Europort.

Local pattern

Tides around Rosslare and the Co. Wexford coast

Wexford has two gauges: Wexford Harbour itself and Rosslare. The county sits where the Irish Sea tide meets the Celtic Sea tide, and the range is the smallest in Ireland. At Rosslare a spring tide moves the water barely 2 m. The times, however, change sharply around Carnsore Point, so use Rosslare for the south coast and Wexford for the long east-facing strands.

Curracloe, Ballinesker and Morriscastle are shelving Blue Flag beaches that swim best around high water. Kilmore Quay and the Saltees on the south coast have strong tidal races, and Duncannon at the mouth of Waterford Harbour is better served by the Dunmore East gauge.

The sand bars at Rosslare Point and Raven Point shift from year to year. Never assume that a bar you walked last summer is still safe to cross.

Questions

About these times

What time is high tide in Rosslare today?

The first high water in Rosslare today is at 09:15 Irish time, 0.8 m above OD Malin. The second high, low waters and the week ahead are in the table above. The data comes from Marine Institute astronomical predictions for the Rosslare gauge.

When is low tide in Rosslare today?

The first low water in Rosslare today is at 03:00 (-0.6 m relative to OD Malin). Low water is the time for the widest strand and for rock pools; the flood usually comes back noticeably within an hour.

How many high tides does Rosslare get a day?

Like all of Ireland, roughly two highs and two lows in every 24 hours and 50 minutes, so tide times shift about 50 minutes later each day.

How big is the tidal range at Rosslare?

Over the next 30 days the range at Rosslare runs from about 0.7 m on the smallest neap tide to 1.8 m on the biggest spring. The 30-day calendar below shows the range for every day.

How accurate are these times?

These are astronomical predictions: the moon and sun are extremely predictable, so times are typically accurate to within minutes. Actual water levels can differ with strong winds and air pressure (storm surge). For navigation-critical decisions, always check official sources.

Reading the table

Understanding the tide table

How to read the table

Each card is one calendar day in Irish local time. High water is marked with a triangle pointing up, low water with a triangle pointing down. The height beside each time is the predicted level in metres above Ordnance Datum Malin, the same datum used on Irish Ordnance Survey maps. A bigger number means more water over the sand, the slip or the rocks.

Most days have two highs and two lows. Every so often a day has only three events. That is normal: the tidal cycle is about 12 hours 25 minutes long, so one high or low slips over midnight into the next day.

The clock runs on Europe/Dublin time, so the tables already account for the change to and from summer time. You never need to add or subtract an hour.

Spring tides and neap tides

Around full moon and new moon the sun and moon pull together and the tide swings furthest: very high highs and very low lows. These are spring tides, and they arrive roughly every two weeks all year round, nothing to do with the season. At the quarter moons the range shrinks and you get neap tides, when the water barely moves off the beach.

You can spot springs in the tables without a calendar. Look for the days where the gap between high and low is largest. Those are the mornings when the widest strand appears at low water, and the evenings when the sea comes right up to the wall.

The largest springs of the year, around the March and September equinoxes, are the ones that flood car parks and coastal roads if they coincide with an onshore gale.

Why weather changes the real level

These predictions only account for the moon and the sun. Air pressure and wind are ignored, because nobody can forecast them weeks ahead. A deep Atlantic low can lift the sea by 30 to 50 cm (a positive surge) and a strong onshore wind piles water against the coast on top of that. High pressure and offshore winds do the opposite.

In practice the times are very reliable and the heights are reliable in settled weather. In a storm, treat the predicted high water as a floor rather than a ceiling, and add the surge that Met Éireann mentions in the sea area forecast.

Best times for swimming, walking and fishing

Swimmers on a shelving beach usually want the hour either side of high water, when the water is deep close in and you are not wading out over 100 m of sand. At steep-to spots such as harbour steps or the Forty Foot, mid tide to high tide is safest because the ladder still reaches the water.

Walkers, rock poolers and dog owners want low water. Aim to arrive an hour before the predicted low, which gives you two hours of falling and slack water before the flood starts to come back in. On sand flats and around tidal islands the flood can return faster than walking pace, so know your low water time before you set off.

Shore anglers generally fish the last two hours of the flood and the first hour of the ebb. Boat owners need the height as much as the time: a slip that dries at 1.0 m is unusable at a 0.6 m low.

Sources and method

Every time and height on this page is an astronomical prediction from the Marine Institute of Ireland for the Rosslare tide gauge, taken from the open IMI_TidePrediction_HighLow dataset on the Institute’s ERDDAP server. We download the data and rebuild every page each night, convert the UTC timestamps to Irish local time (IST in summer, GMT in winter) and group them into calendar days. Nothing is estimated or smoothed by us.

Heights are metres above Ordnance Datum Malin, the reference used on Irish charts and Ordnance Survey maps. To compare with a chart that uses Lowest Astronomical Tide, add the local LAT to OD Malin offset shown on the chart.
