Irish Water Safety is today warning the public of the increased risk to people becoming stranded whilst walking or picking shellfish on our beaches over the weekend.

The moon will be at its closest to earth since 1993 on Saturday March 19th.
This "Lunar Perigee", or 'Super Moon' as some astrologers refer to it as, is the opposite of the "Lunar Apogee", when the Moon is furthest from Earth. Generally, the Moon looks about 12-14% larger at its perigee compared to its apogee.

This has the effect of causing very high and low tides, or increasing the range of the tide. This will expose large areas of beach and rocks which we normally don't see. Many people enjoy walking on our beaches and exploring these new areas of beach and in particular people enjoy picking shellfish to eat which become exposed during these very low tides.

The risk to the public will be of becoming stranded as the tide advances back in which can leave people in a position where they are cut off from the shore. Members of the public are cautioned to be aware of this risk and carry your mobile phone. Should you get in to trouble then call 112 or 999 and ask for Marine Rescue, giving your exact location and in particular if you are near to any conspicuous landmarks nearby to assist the Rescue Services in locating your whereabouts.

All seafarers, surfers, swimmers and divers should be aware of the increased tidal streams that will be running around our coast over the weekend; people could find themselves in peril as a result of these strong and fast tidal conditions which have not been experienced for some time now.

Marine Wildlife Around Ireland One of the greatest memories of any day spent boating around the Irish coast is an encounter with marine wildlife.  It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. As boaters fortunate enough to have experienced it will testify even spotting a distant dorsal fin can be the highlight of any day afloat.  Was that a porpoise? Was it a whale? No matter how brief the glimpse it's a privilege to share the seas with Irish marine wildlife.

Thanks to the location of our beautiful little island, perched in the North Atlantic Ocean there appears to be no shortage of marine life to observe.

From whales to dolphins, seals, sharks and other ocean animals this page documents the most interesting accounts of marine wildlife around our shores. We're keen to receive your observations, your photos, links and youtube clips.

Boaters have a unique perspective and all those who go afloat, from inshore kayaking to offshore yacht racing that what they encounter can be of real value to specialist organisations such as the Irish Whale and Dolphin Group (IWDG) who compile a list of sightings and strandings. The IWDG knowledge base has increased over the past 21 years thanks in part at least to the observations of sailors, anglers, kayakers and boaters.

Thanks to the IWDG work we now know we share the seas with dozens of species who also call Ireland home. Here's the current list: Atlantic white-sided dolphin, beluga whale, blue whale, bottlenose dolphin, common dolphin, Cuvier's beaked whale, false killer whale, fin whale, Gervais' beaked whale, harbour porpoise, humpback whale, killer whale, minke whale, northern bottlenose whale, northern right whale, pilot whale, pygmy sperm whale, Risso's dolphin, sei whale, Sowerby's beaked whale, sperm whale, striped dolphin, True's beaked whale and white-beaked dolphin.

But as impressive as the species list is the IWDG believe there are still gaps in our knowledge. Next time you are out on the ocean waves keep a sharp look out!
