Connected to the Furness Peninsula by a narrow causeway, Roa Island commands views across Morecambe Bay's vast tidal flats. This small settlement grew around its strategic maritime position, with a Victorian pier once serving as a departure point for steamers to the Lake District. The island's distinctive character stems from its working-class heritage and tight-knit community. Today, the exposed mudflats and channels around Roa shift dramatically with the tides, creating a dynamic coastal environment. Walkers and birdwatchers value the island for its vantage points over the bay's ever-changing landscape, while local knowledge of tidal patterns remains essential for safe exploration of this historically significant corner of Cumbria.

Connected to the Furness Peninsula by a narrow causeway, Roa Island commands views across Morecambe Bay's vast tidal flats. This small settlement grew around its strategic maritime position, with a Victorian pier once serving as a departure point for steamers to the Lake District. The island's distinctive character stems from its working-class heritage and tight-knit community. Today, the exposed mudflats and channels around Roa shift dramatically with the tides, creating a dynamic coastal environment. Walkers and birdwatchers value the island for its vantage points over the bay's ever-changing landscape, while local knowledge of tidal patterns remains essential for safe exploration of this historically significant corner of Cumbria.. 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 Roa Island 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, Roa Island 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 Roa Island, 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.
Roa Island is located in Cumbria, North West.
Fish are most active around tide changes, particularly the two hours either side of high and low water. Anglers targeting shore fish near Roa Island use tide predictions to plan sessions when water movement is at its most productive.
Navigating in and out of harbours and estuaries near Roa Island 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.
Many surf breaks and water sports venues near Roa Island 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.
Tidal beaches, coastal paths, and rock pools near Roa Island 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.
The tide chart above plots predicted water height (in metres) against time for Roa Island. 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.
All times shown are in the local timezone for Roa Island (Europe/London). Remember that tide times advance by roughly 50 minutes each day, so always check the chart for your specific visit date.
Most coastal locations, including Roa Island, 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 Roa Island is shown in the chart above.
Astronomical tide predictions for Roa Island 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.
Chart Datum (CD) is the reference level from which all tide heights at Roa Island 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.
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 Roa Island 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.
