Fitzpatrick Bay Beach is a small harbour beach on the Birkenhead shoreline in Auckland 0626, set on the Upper Waitematā Harbour and rated 4.6 on Google by visitors.
Harbour beaches like those along the North Shore work differently from the west coast's surf beaches: the water is calm and sheltered, so the tide shapes the whole visit. At high tide there is usually depth enough for a proper swim, and the flat water suits kayaks and paddleboards; at low tide the bay can empty out to wide flats, better for walking and watching the wading birds than for swimming. Locals check a tide chart before setting out, and after heavy rain it is worth a quick look at Auckland's swimming water quality notices before heading in. Dogs and swimmers often share these shores too, so the local rules on hours and leads are worth knowing.
Quiet and close to the water at Birkenhead, Fitzpatrick Bay is the kind of beach that rewards timing your visit with the tide.
