Last weekends Artic Blast killed an Easter Sunday thru Thursday flounder rally, and although baywater temps have recovered somewhat, the numbers remain on the cool side. Easterly winds yesterday and today, plus new moon tides haven't helped.
The mud flats near the Smith Point Bridge gave up a few fish during the last of the ebb Wednesday afternoon (the bright sun and light winds, too), but the action is still hit or miss.
The flats on the north side of the bay going towards Quogue, and the area between the east end bridges are probably your best best this weekend.
I always check the local shops and marinas beforehand; they always have up-to-the-minute news.
