2018 Gulf Stream Pre-Start Analysis

June 14, 2018

In the final days before the start, the view of the Gulf Stream’s structure and flow is somewhat clouded. By W. Frank Bohlen

Due to persistent cloud cover, satellite views of the Gulf Stream have been less than ideal for navigators looking to plot a winning strategy in the Newport Bermuda Race beginning on Friday, June 15th. However, it’s clear that the pronounced meander in the Stream that was visible for our June 1st report has moved on to the east by 120 miles.

The Stream is now flowing easterly on an axis that is more directly across the course.  However, there are a number of current “features” flowing in circular rotation that will affect boats as they sail on to the south side of the Stream.
