This live stream (below) looks northwards from the Scotsman's Bay shoreline at Sandycove out into Dublin Bay.
Left of screen is Dun Laoghaire's West Pier lighthouse, the harbour mouth and the back of the East Pier itself, showing the town bandstand, the Boyd monument and the lighthouse at the pierhead.
The east bight of the main harbour area is also visible showing yachts on moorings.
Also pictured is the Dublin Port Shipping Lane and in the background is Howth Peninsula and its Baily Lighthouse to the right of screen.
In the midground and only barely visible are Dublin Bay Sailing Club's Pier and Bay Racing Marks.
In the foreground is the Newtownsmith Promenade and its rocky shoreline at low water.
You can compare the live stream webcam pictures (above) with the local weather and sea condition tweets in real-time coming from the Irish Lights Dublin Bay Buoy (below)
