ROFFS™ Northeast U.S. Early Season Preview 2018 PROMISING FEATURES SHOULD LEAD TO A PRODUCTIVE SEASON
ROFFS™ concludes its 2018 spring preview series by providing an overall update of the oceanographic conditions from mid-to-late April offshore of the northeastern United States focusing in on the Mid-Atlantic Bight region and its canyons that includes the zone from Cape Hatteras to Georges Bank into the Gulf of Maine. We again utilized a combination of many different data sets mainly satellite derived sea surface temperature (SST) and ocean color/chlorophyll images. In this article we will discuss the present ocean conditions and what it means for the upcoming late-spring to summer fishing season for the North Carolina to Massachusetts area.
For forecasting short-term oceanographic conditions related to finding fish, ROFFS™ uses real-time direct observations. We have learned that evaluating the preseason conditions along with regional, downscaled climate models provides insight into future seasonal trends for fishing. Experience and understanding the ocean – atmospheric dynamics is our guide as we have had moderate success in forecasting seasonal trends of fishing productivity based on the stepwise progression in the location of the fishes’ preferred habitat based on temperature and water color. Please reference our 2018 Bahamas forecast for more in-depth discussion on the environmental and climate indicators that goes into our detailed evaluation of the eastern United States fishing forecasting analysis (Click Here).
Background and Some Observations for 2018
It is important to look at the year-to-year trends including the anomalies to gain insight into the location and condition of the fishes’ preferred habitat compared with previous years. Comparing similar locations and features to last year during the same mid-to-late April time period we found that the SST of the core of the Gulf Stream off of Cape Hatteras, NC for 2017 was approximately 78.0°F – 78.5°F and for this year it is 1.5°F to 2.0°F cooler (76.0°F – 77.0°F). The SST of the coastal water off of New Jersey, Delaware and Maryland is approximately 1.0°F cooler this year than during the same time period in 2017. Furthermore, the SST offshore of Long Island is also about 1.0°F cooler than this time last year. These and other indicators that will be described below suggest a slightly later arrival or a closer to normal arrival of the main migration of tuna, wahoo, dolphin and billfish into the northeast canyon region this year compared to last year.
One of the main reasons for the cool spring SST’s in the Northeast U.S. region can be attributed to the North Atlantic Oscillation (NAO) switching from a positive phase in February to an extreme negative phase in March. NAO index is based on the atmospheric surface sea level pressure difference between the Subtropical (Azores) High and the Subpolar Low within the North Atlantic Ocean (https://www.ncdc.noaa.gov/teleconnections/nao/). This extreme negative NAO index in March is likely responsible for the cooler than normal temperatures in the eastern United States and also associated with an increase of nor’easters and higher wind events in the Northeast U.S., which is exactly what we have been observing in this region this spring (http://view.surfline.com/eastcoastmarch/8/). Stay tuned or contact ROFFS™ for updated reports of the always-changing ocean conditions related to the best fishing action near your inlet.
The good news is the atmospheric temperatures are finally starting to warm and the SST will start to increase at a more rapid pace as April transitions into May. Also, please see ROFFS™ recent Southeast U.S. Gulf Stream fishing conditions analysis (Click here). These Gulf Stream conditions to the south are usually a good indicator and associated with an abundance of yellowfin tuna and marlin along with other highly migratory species. Recent reports the past two weeks have already confirmed a number of yellowfin tuna catches off of Oregon Inlet to Cape Hatteras, NC, where you find the Gulf Stream filaments and Gulf Stream edges. Based on historical observations we anticipate that these fish along with other tuna, dolphin, wahoo and then billfish will move to the northeast U.S. region from the Gulf Stream and into the relatively large eddy features that move over the canyon areas. Additional good news is that wahoo, dolphin, tuna and sailfish have already been caught off of South Carolina, North Carolina and northern Florida suggesting these species are already within the Gulf Stream and migrating north and soon (if not already) within the northeastern U.S. waters when the habitat is favorable.
