Sailing Conditions at Penarth Yacht Club

 

General.

  The beach off  Penarth runs approximately north to south, with the pier and Penarth head to the north of the club.  The Outer Wrack, a west cardinal buoy, is about  400 m east of the pier. Flatholm island lies about 6km to the SE. A conical orange buoy about 300m east of the club is used as an outer distance mark for club races.  The courses for Open meetings and regattas are set about a kilometre east of the shore. Here the wind is relatively steady, and it is clear of the shipping lane.

 Wind

   The wind is  largely unaffected by the land in the normal sailing area for open events.  An onshore summer thermal breeze occurs occasionally. When it does, it is in the late afternoon and lasts only about an hour.

 The prevailing wind is from the South West. This produces a belt of disturbed wind reaching out about 200m beyond the ODM.  The slipway is very sheltered, so there may be more wind than you think.

  North Easterly winds are fairly common. There is little backwind effect from the cliffs behind the slipway, so what you see is what you get.

Tides

  The tide at Penarth goes up and down like a lift.  Spring tides have a range of about 13metres, neap tides about 9m. In the normal sailing area for open events, the direction changes close to high water time. The flood tide runs towards the North or NE from one to two knots.   The ebb runs to the South, and is slightly stronger.

  Closer inshore things are more complicated. The ebb sets in about one and a half hours before high water, and the tide line slowly moves out to beyond the ODM, vanishing at high water. 

Shipping

   All Commercial traffic entering and leaving Cardiff dock passes between the Pier and the Outer Wrack.  Large vessels usually approach and leave from the direction of Flatholm.   They have priority throughout the sailing area, and small craft must keep clear at all times.

 Launching + Landing

  Please don’t block the slipway while you rig your boat, and leave room for pedestrians to pass on the promenade.
