ROFFS™ continues its spring preview series by providing an overall update of the oceanographic conditions during early April for the east coast of the United States from the Florida Keys north to Cape Hatteras, NC including the entire offshore Gulf Stream region. As always, we use a combination of many different data sets but mainly sea surface temperature (SST) and ocean color/chlorophyll images. We will discuss these overall ocean conditions for the present spring season and how these conditions may translate to the near future fishing season.
For forecasting short-term oceanographic conditions related to finding fish, ROFFS™ uses real-time direct observations rather than unproven ocean models and longer-term composites. We have learned that evaluating the preseason conditions along with regional 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 2017 Bahamas forecast for more in-depth discussion on the environmental and climate indicators that goes into our detailed evaluation of the southeastern United States fishing forecasting analysis (Click Here).
Background and Some Observations for 2017
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 early April time period we found that the SST of the core of the Gulf Stream off of Miami, FL for 2016 was approximately 80.1°F and for this year it is approximately the same (79.6°F). Farther north off of Charleston, SC the SST of the core of the Gulf Stream for early April 2016 was approximately 78.0°F and for this year it is also relatively similar (78.5°F). However, farther north off of Cape Lookout, NC, the SST of the core of the Gulf Stream for 2016 was approximately 76.0°F – 76.5°F and this year the SST is approximately 77.5°F – 78.0°F, which is 1.5°F higher than last year during this same early April time period. Therefore, the farther north you go the Gulf Stream SST overall appears to be warmer this year than last year. This could indicate an earlier arrival of tuna, wahoo, dolphin and even marlin farther north off of South Carolina and North Carolina this year compared to last year, especially when considering that the conditions over the Bahamas region is more favorable than previous years.
