ROFFS FISHERIES OCEANOGRAPHIC ANALYSIS FOR THE SHINNECOCK TO NANTUCKET OFFSHORE AREA (LAT./LONG.)
SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***SAMPLE***
Based on a multiple factor analysis, the symbols (hot spot spots) mark the areas where bait concentrations are expected and where fishing action is expected to be better compared with other (non-marked) areas. These are not based on dock rumors or hearsay fishing reports. Fishing reports are stated as such. You should start fishing where you recognize other signs of good fishing conditions near these marked areas. It is very important to use your sea surface temperature (sst°) gauge to locate the boundaries of the water masses, which are outlined. Rather than trying to find water based on the absolute temperature values shown on the map,  search for the relative change in sst where the water mass boundaries occur. Arrows indicate the main current direction. Numbers inside of the dots indicate the number of consecutive days that we have seen favorable conditions in that location.

We are able to observe the ocean conditions in this area relatively clearly today using a combination of infrared satellite imagery from late this morning and early this afternoon. Overall, we continue to observe the northern edge of a large pool of blue 78.4°F-81.3°F Gulf Stream water pushing inshore over the 100 fathom curve of Block and West Atlantis Canyon providing good chances for fishing action with tuna, dolphin, wahoo and billfish especially where favorable conditions have remained stable for multiple days. Inshore of 100 fathoms, filaments of blue 74.3°F-77.2°F water has been pulled inshore over 30-50 fathoms due to the westward movement of cooler 73.1°F-71.4°F green water originating from the Nantucket Shoals. Increased chances for action is also likely along the inshore edges of these filaments of blue water where they occur over good bottom areas. South of Long Island, we continue to observe the slow northeast movement of blue green 75.5°F-77.2°F water pushing inshore over 20 fathoms producing strong green to blue green boundary zones that will provide increased chances for a combination of tuna and shark action. As you continue eastward from Montauk, the ocean conditions appear unstable and blending as scattered chances for fishing action will occur where the cooler westward moving green water forms boundaries with the warmer blue green water south of Martha’s Vineyard and just west of Davis South Shoals.
With this in mind, the ocean conditions suggests your better chances for tuna, dolphin, wahoo and marlin action will occur along the northern edges of the filaments of blue 75.5°F-78.4°F water as they are being pulled inshore over the 40-50 fathom ledges and where favorable conditions have remained stable for 2-3 days from near 71°22’W & 40°15’N eastward to near 71°14’W & 40°16’N to near 70°58’W & 40°17’N, as well as, inshore between 30 and 40 fathom depths near 70°55’W & 40°27’N to near 70°41’W & 40°30’N. If you find that the filaments of blue water are not as productive as we believe, we suggest you continue further offshore and fish the northern edge of the dark blue 80.1°F-81.3°F Gulf Stream water that continues to occur over the 100 fathom ledge in Block and Atlantis Canyons for 2-6 days from over the Dip near 71°44’W & 39°55’N to the Fish Tails near 71°15’W & 40°01’N to near 71°00’W & 40°05’N, and into West Atlantis Canyon before the blue Gulf Stream water starts to get pulled offshore near 70°32'W & 40°03’N. As you continue eastward into East Atlantis Canyon and Veatch Canyon, good chances for action will also occur along the northern edge of a finger of blue 76.9°F water where favorable conditions have remained for 2-3 days from near 70°20’W & 40°10’N eastward to near 69°45’W & 40°08’N.
South of Long Island, the ocean conditions suggest increased chances for fishing action with tuna and sharks will occur along the green to blue green 73.1°F-76.3°F boundary zone where it lies over 20-25 fathom depths from 71°32’W & 41°05’N to near 71°45’W & 40°55’N to near 72°00’W & 40°45’N to south of Shinnecock Inlet and Moriches Inlet near 72°20’W & 40°45’N to 72°32’W & 40°39’N. Further offshore, good chances for action will occur along the warmer to cooler (76.3°F-74.3°F) offshore edge of the blue green water where favorable conditions have remained for two days over Suffolk near 71°15’W & 40°52’N, over Ryan’s Horn near 71°28’W & 40°45’N, and over the Ranger near 71°37’W & 40°34’N where favorable conditions have remained for six days. Additional chances for action may occur west of Ranger where favorable conditions occur over 30 fathoms near 72°10’W & 40°34’N, 71°59’W & 40°28’N, and over Maiden Creek near 72°05’W & 40°13’N. Offshore of Nantucket, favorable conditions for fishing action have remained stable for the past two days along the western edge of the cooler green 65.7°F water where it lies over 20 fathoms near 70°20’W & 40°59’N, and over the 30 fathoms near 70°10’W & 40°36’N.
