Tide times Wicklow

Wicklow Harbour is a small commercial and fishing port below Wicklow town. Its gauge serves the town's own beaches and Brittas Bay and Silver Strand to the south, the county's busiest summer strands.

Today, Fri, 16 Oct: high water at 03:55 (0.6 m) and 16:10 (0.8 m), low water at 09:00 and 21:50. 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 Wicklow Harbour, Brittas Bay, Silver Strand.

Local pattern

Tides around Wicklow and the Co. Wicklow coast

The Wicklow coast runs almost straight from Bray Head to Arklow, and the tide sweeps along it as a progressive wave from north to south. High water at Arklow is roughly an hour later than at Bray, so pick the nearest station rather than assuming the county has one time.

Off Wicklow Head the tidal streams are among the strongest on the east coast, with an eddy that catches yachts and kayaks unawares. The shingle beaches at Bray, Greystones and Kilcoole shelve steeply and swim well at any tide, while Brittas Bay is a classic shelving strand with long dunes and a big drying area at low water.

Range is small here, under 3 m at springs and barely 1.5 m at neaps, so the height column changes less than on the west coast. Wind has a proportionally bigger effect: a strong easterly can add half a metre to a Wicklow high tide.

Questions

About these times

What time is high tide in Wicklow today?

The first high water in Wicklow today is at 03:55 Irish time, 0.6 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 Wicklow gauge.

When is low tide in Wicklow today?

The first low water in Wicklow today is at 09:00 (-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 Wicklow 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 Wicklow?

Over the next 30 days the range at Wicklow runs from about 0.9 m on the smallest neap tide to 2.5 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 Wicklow 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.
